	* tools/pdbgen/pdb/help.pdb: changed "prog_name" parameter of
	gimp_help() to "help_domain". It's useless to pass the plug-in's
	executable name to the core because the core already knows it.
	Instead, enabled accessing arbitrary help domains via the
	PDB. Passing NULL as help_domain will use the domain the plug-in
	registered, or the GIMP main help domain if it didn't register a
	domain.

	* app/pdb/help_cmds.c
	* libgimp/gimphelp_pdb.[ch]: regenerated.

	* libgimp/gimpui.c (gimp_ui_help_func): pass NULL as help_domain.
