* Fixed issue that cache is tried to be cleared even if a relation is changed

* fixed a potential bug in Persistence_Query. Please review @Jochen!

* Implemented the handling of values === NULL in Queries; related to #3838 (needs feed-back)
* Changed all calls to t3lib_div::makeInstance('Tx_Extbase_Persistence_Manager') to Tx_Extbase_Dispatcher::getPersistenceManager()
* Fixed conversion of DateTime objects in Query values
* Eliminated unnecessary braces
* Fixed "NOT" ( from "(NOT foo='bar')" to "NOT (foor='bar')" )

* Implemented a static function Tx_Extbase_Dispatcher::getPersistenceManager()
* Changed Repository to invoke Tx_Extbase_Dispatcher::getPersistenceManager()
* These changes should enable the Repository to be called from outside (itemProcFunc); related to #3899

* The Persistence Backend will now be injected via setter injection rather than via constructor injection. The Persistence Manager can be reached at any "place" via t3lib_div::makeInstance('Tx_Extbase_Persistence_Manager') after its first initialization (in the Dispatcher).

* Changed Argument: Check for is_object($result) instead of $result !== NULL prevents fatal error; empty result should be catched anyway
* Change: The database handler is now injected to the Typo3DbBackend (for better testability)
* bindVariable() uses now a unique variable name; resolves #3885
* Typo3DbBackend: the variable $sql (and its subparts) are now initialized as arrays (related to #3885 and #3826)
* Typo3DbBackend: Implemented a class variable $useEnableFields (by now only used for better testability)

* Implemented cache clearing by TYPO3s clearCacheCmd. This is not particularily fine-grained, but works. references #3421
* Made AbstractEntity have a different compare method inside _isDirty() which compares objects in-depth, and not just their references.

* added small comments and cleaned up PHPDoc

* The SQL string should be syntactically correct now (needs some more testing)
* Implemented a test before calling enableFields()

* Fixed internal method _memorizeCleanState($propertyName); nothing was memorized if $property name was set
* Removed call to $GLOBASL['TYPO3_DB']->fullQuoteString() as this should be the job of the persistence backend
* Fixed Query and Query Object Model Factory (patch contributed by Frans van der Veen); Resolves #3879
* Removed obsolete commit() method in Session
* Fixed invalid SQL without enableFields; Resolves #3826
* First step taken to implement the parsing of Orderings

* Fixed typo in Action Controller; Resolves #3531

* Reviewed code
* Biggest issue: Objects must be registered manually as reconstituted in the Persistence Session. I think this should be done by the data mapper.
* I still need to understand JOINs and relations fully.

* Removed unused class Literal
* Added check for having the same number of $parameters and placeholders ("?") in a statement

* Added some review comments for Extbase persistence rewrite

* Change: Using $GLOBALS['EXEC_TIME'] instead of time(); resolves #3782
* Fixed: back-ported LiteralInterface

(Changes by Jochen)
This commit merges the rewrite of the persistence layer back to trunk. It will probably break your existing installation. Please check out fluid and blog_example again.
* Implemented an Object Manager (a wrapper for t3lib_div::makeInstance())
* !!! Backport of the Query and the Query Object Model from FLOW3.
* !!! Removed Repository->fetch*()
* Splited the functionality of the Object Relational Mapper into the Persistence Backend, the Data Mapper and the SQL Storage Backend.
* Implemented the Lazy Loading Proxy.
* supported Request types is now Tx_Extbase_MVC_Request instead of Tx_Extbase_MVC_Web_Request.
* Changed _reconstituteProperty() to _setProperty() (according to FLOW3).
* Added _getProperty() to the Domain Object.
* The Dispatcher now instanciates and uses a PersistenceManager to commit changes.
* Added TypoScript converter method (to convert from new TS to classic TS). Fixes #3293.
* Renamed SqlBackend to Typo3DbBackend
* Now using constants in Tx_Extbase_Persistence_PropertyType instead of Tx_Extbase_Persistence_Mapper_ColumnMap
* Improved conversion from table value to property value
* Persistence_Repository: findByUid() checks now for positive integer
* Fixed: Only Aggregate Roots are now registered as Reconstituted Objects
* !!! Added _isNew() to the Domain Object Interface
* Revision of the Persistence Backend (CRUD operations work now - again)
* Fixed Query Object Model "UpperCase"
* Implemented addRow(), deleteRow() and updateRow()
* Fixed: _memorizeCleanState() now clones a property value if it is an object
* Argument->findObjectByUid() memorizes now the clean state (todo: check if the object is an Aggregate Root)
* Removed unnecessary method getRelations()
* Fixed wrong class name of PropertyError; resolves issue #3855
* Fixed typo in Persistence Query; resolves issue #3831
* Changed: Equivalent Value Objects (all properties are equal) are now persisted only once
* Backport and enhanced several Unit Tests (not finished yet)
* Enhanced Base Test Case
* Changed signature of hasValueObject()
* Changed: hasValueObject() returns the uid of the already persisted value object - if any
* Fixed: relation tables are now filled with the right values if a value object already exists in the database
* Changed: The Persistence Manager and the Query Factory are now "injected" into the Arguments and Argument
* Deleted obsolete files

[+FEAT]: Added TypoScript converter method (to convert from new TS to classic TS). Fixes #3293.

* Added injectSettings evaluation, so settings are passed to the View (fixes #3413)

* Added Reflection Cache patch by Niels Pardon. Thanks a lot! (fixes #3294)

* Tx_Extbase_MVC_Web_Routing_URIBuilder:
  * $additionalArguments is an array now. URIFor() merges additionalArguments with arguments. Fixes #3575
  * DomainObjects in arguments are now replaced recursively. DomainObjects are replaced in additionalArguments too.
  * cache hash is disabled if noCache is set
  * added test cases
  * some smaller tweaks and typo-fixes
* Fixed Tx_Extbase_MVC_Controller_AbstractController_testcase - was still refering to "Tx_Extbase_MVC_View_Helper_URIHelper"

* Removed new lines after ?>; resolves #

* Backported major changes from FLOW3 to Extbase.
* !!! Some of these changes are not backwards-compatible!
* MVC:
** Controller:
*** Added ControllerContext
*** AbstractController:
**** !!! removed initializeArguments(). Use ActionController::initializeAction() instead.
*** ActionController:
**** !!! removed $initializeView
**** !!! new method signature of protected function initializeView(Tx_Extbase_View_ViewInterface $view)
** View:
*** !!! Removed Helper (and URIHelper)
**** !!! URIHelper has been moved to MVC_Web_Routing_URIBuilder and can be accessed through $this->controllerContext available in View and (Fluid) ViewHelpers
*** AbstractView:
**** !!! removed $request
**** removed $viewHelpers
**** !!! removed getViewHelper()
**** removed $contextVariables
**** added $controllerContext
* Validation:
** !!! ValidatorResolver: now internal! You should not need to use it!
** !!! renamed ChainValidator to ConjunctionValidator
** Introduced PropertyError
** Added new validators (f.e. DisjunctionValidator and some others missing from FLOW3)

* Started to backport the test cases for the Repository

* Removed debug code
* Removed TODO comment (now issue on forge) 

* Added comment to all backported FLOW3 classes ("Credits go to v5 team")

* Tx_Extbase_Utility_Plugin::registerPlugin(): removed debug code
* re-implementet underscoredToUpperCamelCase() in Utility Plugin

* Changed Tx_Extbase_Utility_Plugin::registerPlugin(): You are now free to choose whether you want to pass the extension name (in UpperCamelCase) or the extension key available in $_EXTKEY (in lower_underscore) as first argument

* Fixed wrong class name of Tx_Extbase_Utility_Plugin_testcase (not mission critical)

* Added a new registerPlugin() method to Extbase
UtilityTx_Extbase_Utility_Plugin::registerPlugin('BlogExample', 'Pi1', 'A Blog Example', array('Blog' => 'index,show,edit'));
* Added Unit Tests

* Some minor code cleanup
* Added some release notes

* changed the default value of the section parameter from NULL to '' as that's the default of the link/uri view helpers of Fluid.
* The check whether $section is set was not type-safe. fixed that.

* Corrected all @package and @subpackage annotations
* added preliminary @internal annotations
* Fixed URIHelper based on a patch by Bastian Waidelich
* Set version number in ext_emconf.php to 0.9.0
This version can now go into TYPO3 4.3 alpha3.

* Removed all Query related class files and tests (will be reverted after TYPO3 4.3alpha3 was released)

* Changed all method calls using Tx_Extbase_Utility_Strings to the correspondant t3lib_div methods
* Deleted Tx_Extbase_Utility_Strings

* Extensive code cleanup
* Deleted obsolete files

* Removed outdated documentation files

* TypoScriptSource: All trailing dots are removed recursively from TypoScript Settings. The node value (like 10 = TEXT) is now stored assigned to a "private" array key called "_typoScriptNodeValue".

* Done some more remaining renaming from pluginKey to pluginName

* Done some remaining renaming from pluginKey to pluginName
