	* app/actions/file-commands.c (file_save_cmd_callback): don't
	g_return_if_fail() if there is no active drawable, just silently
	return.

	* app/actions/image-commands.c: remember the last merge_type of
	the "Merge Visible Layers" dialog.

	* app/actions/layers-commands.c: remeber the last values of the
	"Add Layer Mask" dialog.

	* app/actions/select-commands.c: renamed a bunch of static
	variables to be consistent with other variables used to remember
	dialog values.

	* app/actions/view-commands.c (view_fullscreen_cmd_callback): it's
	useless to update the "view-fullscreen" actions here because the
	"fullscreen" state of the shell changes asynchronously
