	* libgimpbase/gimpbasetypes.h: changed GimpDatafileLoaderFunc to
	take a separate "gpointer user_data" parameter (passing user_data
	in a struct was a quite nonstandard API design). Made the
	GimpDatafileData pointer const.

	* libgimpbase/gimpdatafiles.[ch]: removed user_data from the
	GimpDatafileData struct and added "const gchar *basename" so we
	don't need to g_path_get_basename() in many callbacks.

	* libgimp/gimpmiscui.[ch]: changed gimp_plug_in_parse_path() to
	gimp_plug_in_get_path() and return the unparsed path.

	* app/core/gimpdatafactory.c
	* app/core/gimpenvirontable.c
	* app/gui/gui.c
	* app/plug-in/plug-ins.c
	* libgimpmodule/gimpmoduledb.c
	* plug-ins/script-fu/script-fu-scripts.c: changed accordingly.

	* plug-ins/FractalExplorer/Dialogs.c
	* plug-ins/FractalExplorer/FractalExplorer.[ch]
	* plug-ins/FractalExplorer/Globals.c
	* plug-ins/gfig/gfig.c
	* plug-ins/gflare/gflare.c: use gimp_datafiles_read_directories()
	instead of fiddling with g_dir_open() manually. Random cleanups.
