* configure.ac Makefile.am: auto-ize.
* xdgmime/: Add freedesktop.org MIME spec implementatin
by Jonathan Blandford.
* gtkfilesystem.[ch]: Add gtk_file_info_render_icon()
gtk_file_info_set/get_icon_type to do icon handling
based on MIME type. Add a simple icon caching system.
* gtkfilesystemgnomevfs.c: Implement ensure_types()
so that extending the set of types for a loaded
directory works. Set the MIME type to get the default
icon handling.
* gtkfilesystemunix.c: Look up the MIME type using
xdgmime.
* gtkfilechooserimpldefault.c: Display icons in the list.
