	* app/display/gimpdisplayshell-callbacks.c: factored out utility
	function gimp_display_shell_update_focus() which sets the active
	tool into the proper state after the canvas received focus.

	(gimp_display_shell_canvas_tool_events): use it here instead of
	duplicating the code 3 times.

	(gimp_display_shell_ruler_button_press): use it here too so the
	move and color tools don't do weird things in click-to-focus
	mode (when FOCUS_IN is delivered after BUTTON_PRESS).
