Subject: js: Add keyboard navigation for menus

Once the input focus is in the menu system (for instance by Shift+Tab
from the puzzle), you can move left and right through the menu bar and
up and down within each menu.  Enter selects a menu item.  The current
menu item is tracked by giving it the input focus.
