	* app/core/gimpmarshal.list
	* app/widgets/Makefile.am
	* app/widgets/widgets-types.h
	* app/widgets/gimpcellrendereraccel.[ch]: new cell renderer
	which displays an accelerator and allows to edit it (ripped
	out of libegg and modified).

	* app/widgets/gimpactionview.c: use the new renderer and connect
	to its "accel-edited" signal (its callback is one huge mess that
	needs to be cleaned up). Added ugly hack to work around GTK+ API
	limitation that seems to prevent implementing a shortcut editor in
	a sane way.

	* app/actions/file-actions.c
	* app/actions/image-actions.c
	* app/actions/tools-actions.c: added ugly hacks here, too.

	* app/gui/preferences-dialog.c: relaced Cancel/Ok in the shortcut
	editor by Close.
