	Added an API to allow plug-ins to embed the progress for the
	actions they trigger into their own GUI (attention: half-done and
	broken code ahead...)

	* app/core/Makefile.am
	* app/core/core-types.h
	* app/core/gimppdbprogress.[ch]: new object implementing dispatching
	progress calls to a temporary PDB procedure in a plug-in.

	* app/Makefile.am: force to link gimppdbprogress.o, bah!

	* app/plug-in/plug-in-progress.[ch]: added API to install,
	uninstall and cancel a PDB progress for this plug-in, but disabled
	the implementation because it doesn't work yet.

	* tools/pdbgen/pdb/progress.pdb: added pdb wrappers for the new
	install, uninstall and cancel functions.

	* libgimp/Makefile.am
	* libgimp/gimp.h
	* libgimp/gimpprogress.[ch]: added an API around the PDB progress
	stuff.

	* app/pdb/internal_procs.c
	* app/pdb/progress_cmds.c
	* libgimp/gimpprogress_pdb.[ch]: regenerated.

	* plug-ins/script-fu/script-fu-scripts.c: use the new API to show
	the progress in the script-fu dialog.
