This patch moves a whole lot of the menu logic from WSWindowManager to its proper home in WSMenuManager. We also get rid of the "close_current_menu()" concept which was easily confused in the presence of submenus. All operations should now be aware of the menu stack instead. (The concept of a single, current menu made a lot more sense when there were no nested menus.)
