	* app/widgets/gimpdnd.h: removed enum GimpDndType...

	* app/widgets/widgets-enums.h: ...and added it here.

	* app/widgets/gimpdnd.c: added more g_return_if_fail(). Allow
	all gimp_dnd_foo_dest_add() functions to be called without
	callback (just add the target if callback is NULL).

	(gimp_dnd_open_files): removed the checks for validity of the
	passed filenames/uris...

	(gimp_dnd_set_file_data): ...and added it here so all callbacks
	get an already sanitized list of strings.
