	* app/plug-in/plug-in.[ch]: badly chopped into the new files below.
	Pass around much more "PlugIn" and "Gimp" pointers instead of
	using "current_plug_in" and "the_gimp". Needs much more hacking
	though... :(

	* app/plug-in/Makefile.am
	* app/plug-in/plug-in-def.[ch]
	* app/plug-in/plug-in-params.[ch]
	* app/plug-in/plug-in-progress.[ch]
	* app/plug-in/plug-ins.[ch]: new files.

	* app/gui/Makefile.am
	* app/gui/plug-in-commands.[ch]
	* app/gui/plug-in-menus.[ch]: ditto.

	* app/plug-in/plug-in-rc.c
	* app/plug-in/plug-in-types.h: changed accordingly.

	* app/pdb/procedural_db.c: changed procedural_db_destroy_args()
	so it can be used from plug_in_args_destroy(). Fixed a parasite
	memory leak (or introduced a new SEGV, we'll see...).

	* app/display/Makefile.am: another "truly ugly hack" until the
	plug-in menu stuff is chopped even more...

	* app/gui/commands.[ch]: removed filter...
