	* app/pdb/gimp-pdb.c (gimp_pdb_register)
	(gimp_pdb_unregister): ref all registered procedures.

	* app/xcf/xcf.c
	* tools/pdbgen/app.pl: unref newly created procedures after
	registering them.

	* app/core/gimp.[ch]: renamed member "plug_in_proc_defs" to
	"plug_in_procedures". Renamed "proc_def" variables to "procedure".

	* app/actions/plug-in-actions.c
	* app/menus/plug-in-menus.c: changed accordingly.

	* app/plug-in/plug-ins.[ch]: keep a reference to all procs which
	are in gimp->plug_in_procedures.

	(plug_ins_exit): unref them all and free the list. Apparently we
	were leaking them before on exit.

	* app/plug-in/plug-in-def.[ch]: s/proc_defs/procedures/. Ref
	procedures added with plug_in_def_add_procedure(). Added
	plug_in_def_remove_procedure() which unrefs them again. Removed
	"free_proc_defs" parameter from plug_in_def_free() and always
	unref the procedures.

	* app/plug-in/plug-in.[ch]: added plug_in_add_temp_proc() and
	plug_in_remove_temp() proc. Ref the added procedures.

	* app/plug-in/plug-in-message.c: use the new APIs instead of
	adding/removing procs and temp procs from their lists manually.
	Unref the newly created procedure after adding then to the
	plug_in_def or plug_in.

	* app/plug-in/plug-in-rc.[ch]
	* app/plug-in/plug-ins-query.c
	* tools/pdbgen/pdb/plug_in.pdb: changed accordingly.

	* app/pdb/*_cmds.c: regenerated.
