	* app/plug-in/plug-in.[ch]: renamed plug_in->busy to
	plug_in->in_temp_proc. Added a stack of GMainLoops to each
	plug-in. Added the "current_return_vals" to the PlugIn
	struct. Renamed plug_in_kill() to plug_in_exit(). Removed
	the stuff added below. Cleanup.

	* app/plug-in/Makefile.am
	* app/plug-in/plug-in-message.[ch]
	* app/plug-in/plug-in-run.[ch]
	* app/plug-in/plug-in-shm.[ch]: new files taking out functionality
	from the overloaded plug-in.c. Added the code back in that implements
	temp proc return messages (inside an #ifdef) because i don't
	really get why it was removed on Sep 19 1998.

	* app/plug-in/plug-ins.c: changed accordingly.

	* app/plug-in/plug-in-def.c
	* app/plug-in/plug-in-params.c: removed inclusion of <gtk/gtk.h>.

	* app/gui/file-save-dialog.c
	* app/gui/paths-dialog.c
	* app/gui/plug-in-commands.c
	* app/gui/plug-in-menus.c
	* app/pdb/procedural_db.c
	* app/widgets/gimphelp.c: changed plug-in includes accordingly.

	* app/gui/plug-in-commands.c: don't use "the_gimp" from
	"app_procs.h" but get it from the GimpItemFactory that invoked the
	plug-in callback.
