	* app/apptypes.h: added the datafile loader_func typedefs.

	* app/datafiles.h: removed from here.

	* app/gimpcontainer.[ch]: emit "freeze" and "thaw" signals to get
	rid of those blah_select_[freeze|thaw]_all() stuff.

	* app/gimpdatalist.[ch]: new function gimp_data_list_load() which
	takes a va_list of GimpDataObjectLoaderFuncs and file extensions
	and is almost a replacement for the four files below.

	* app/brushes.c
	* app/gradients.c
	* app/palettes.c
	* app/patterns.c: very simple now. It may be worth thinking about
	making all GimpData subclasses managed by a descriptive array in
	the context_manager.
