	* libgimpbase/gimpbaseenums.h (enum GimpProgressCommand):
	added GIMP_PROGRESS_COMMAND_PULSE.

	* libgimpbase/gimpbaseenums.c
	* plug-ins/pygimp/gimpenums.py
	* tools/pdbgen/enums.pl: regenerated.

	* app/core/gimppdbprogress.c: implement GimpProgress::pulse()
	and send a PULSE command to the callback.

	* libgimp/gimpprogress.c: handle PULSE by calling the set_value()
	callback with a value of -1 and document that hack in the API docs.

	* libgimp/gimpprogressbar.c: interpret -1 as request to pulse.
