	Added basic support for using the online user manual:

	* app/widgets/gimphelp.c
	* plug-ins/help/gimphelp.c: moved some help logic to the core. 
The
	default help domain is now constructed in the core and passed to
	the help plug-ins just like the plug-in help domains.

	* app/config/Makefile.am
	* app/config/gimprc-blurbs.h
	* app/config/gimpguiconfig.[ch]: added gimprc properties to
	specify the location of the online user manual and to decide if 
it
	should be used instead of a locally installed copy.
