	Finished some work that Brix started on the help system. It's
	now possibly to use an external web-browser for context help
	(bug #136081):

	* configure.in
	* plug-ins/Makefile.am
	* plug-ins/help/Makefile.am
	* plug-ins/help/domain.[ch]
	* plug-ins/help/help.c: new plug-in that does the help domain
	management. Most of this used to live in the helpbrowser plug-in.

	* plug-ins/helpbrowser/Makefile.am
	* plug-ins/helpbrowser/domain.[ch]: removed these two files here.

	* plug-ins/helpbrowser/helpbrowser.c: changed accordingly.

	* app/widgets/gimphelp.c: use the new help plug-in.
