== imagebrowser ==

Initial commit of imagebrowser in trunk.
BIG COMMIT!

Main changes:
* completely reworked imasel space
* creation and storage of the preview images for materials, textures, world and lamp
* thumbnails of images and movie files when browsing in the file system
* loading previews from external .blend when linking or appending
* thumbnail caching according to the Thumbnail Managing Standard: http://jens.triq.net/thumbnail-spec/
* for now just kept imasel access mostly as old imgbrowser (CTRL+F4, CTRL+F1) a bit hidden still.
* filtering of file types (images, movies, .blend, py,...)
* preliminary managing of bookmarks ('B' button to add, XKEY while bookmark active to delete)

More detailed info which will be updated here: http://wiki.blender.org/index.php/User:Elubie/PreviewImageBrowser

Places that need special review (and probably fixes):
* BLO_blendhandle_get_previews in readblenentry
* readfile.c: do_version and refactorings of do_library_append
* UI integration

TODO and known issues still:
* Accented characters do not display correctly with international fonts
* Crash was reported when browsing in directory with movie files
* Bookmark management still needs some UI work (second scrollbar?), feedback here is welcome!

Credits:
Samir Bharadwaj (samirbharadwaj@yahoo.com) for the icon images.

Many thanks to everyone who gave feedback and helped so far!
