	* app/app_procs.c: make absolute paths out of relative ones
	passed on the commandline so the GimpImagefiles can generate
	previews.

	* app/gui/Makefile.am
	* app/gui/drawable-commands.[ch]: new files implementing menu
	callbacks which work not just on layers.

	* app/gui/layers-commands.[ch]: removed them here. Cleanup.

	* app/gui/menus.c: changed accordingly.

	* app/gui/brushes-commands.c
	* app/gui/channels-commands.c
	* app/gui/vectors-commands.c: cleanup. Added macros to get
	rid of code duplication.
