	* app/Makefile.am
	* app/lc_dialogP.h
	* app/paths_dialogP.h: removed stuff that will go away anyway (put
	the declarations to the public headers).

	* app/gimpui.[ch]: new function gimp_widget_get_callback_context()
	which may only be called from a *_cmd_callback() and returns the
	data we attached with weird methods.

	* app/gui/Makefile.am
	* app/gui/channels-commands.[ch]: callbacks independent from the
	channels dialog and the "new" and "edit channel" dialogs.

	* app/gui/channels-dialog.[ch]
	* app/gui/layers-commands.c
	* app/gui/layers-dialog.[ch]
	* app/lc_dialog.[ch]
	* app/gui/menus.c
	* app/gui/paths-dialog.[ch]
	* app/tools/gimpbezierselecttool.c
	* po/POTFILES.in: changed accordingly.
