	* app/plug-in/plug-in-types.h
	* app/plug-in/plug-in-proc-def.[ch]: renamed to GimpPlugInProcedure
	and made a GObject derived from GimpProcedure (instead of having
	a pointer to a GimpProcedure). Added image_types and file_magic
	utility functions taken from plug-ins.[ch]. Still lives in the
	same crappy files because I am undecided where to put it...

	* app/pdb/gimpprocedure.c (gimp_procedure_real_execute): removed
	switch() statement and always call the internal marshaller because
	GimpProcedure::execute() is properly overridden by
	GimpPlugInProcedure now.

	* app/plug-in/plug-ins.[ch]: removed the mime_type and file_magic
	utilities added to GimpPlugInProcedure.
