	* app/menus.c
	* app/nav_window.c

	Nav window code now handles boundary conditions correctly (ie
	you can scroll to the edges of the image now).
	It also has some key bindings:-

	1) Arrow keys work as expected
	2) =/- keys perform zoomin/zoomout. Note these keys are hardcoded
	at present until (if) I find away of finding out how to get the
	current accel. keys for these functions.
	3) Space will raise the display window to the top of the window stack.
	It also updates the preview. This will be changed to happen
	automatically RSN.

	Tearoff menus are now popped up and down (like other dialogs) when
	the tab key is pressed in the image window.
