With the introduction of FAL the files and folders are
objects and so there is more info than just a name/extension
to determine the right icon. And with file_metadata
you have the possibility to even add more info to
a file (access rights etc).

This patch adds a new method to the IconUtility API for
generating the sprite icon for a resource. There is also
a hook where other extensions can hook in and change
the icon, options and overlays.

Furthermore, all calls in the core are changed to
IconUtility::getSpriteIconForFile where a
File or Folder object was available.
