Created 'More menu' widget and added it to the unplaced unit token

Created the more menu widget. Added the more menu widget to the unplaced unit token. Also a drive by to add the correct shadow to the unplaced unit token.
`.menu` will be wrapped in `.yui3-moremenu` which is what we reference, `.menu` is only used to reference that element that is shown/hidden. I could actually do away with that class altogether and just show/hide the whole widget.
