* Modified typo3/sysext/cms/tslib/class.tslib_content.php:
	* fixed bug: When providing an imgList for the IMGTEXT TLO, no spaces were accepted in the comma separated list. Now using t3lib_div::trimExplode for splitting.
	* fixed bug: The alt and title parameters have not been set correctly when using IMGTEXT with the imgList property. Now everything works as expected: You may specify alt/title texts for the whole IMGTEXT, or for each imgObj independently

* Added support for automatically caching image dimensions instead of executing IM identify.  Original extension provided by Michael Stucki.
	* Affected files: t3lib/class.t3lib_stdgraphic.php, typo3/sysext/cms/ext_tables.sql
	* Tested by Ingmar, Michael and Robert
