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.
This can be moved to the `bindUI` method. You also don't need the `addEvent` functionality in a widget because these events are attached to the bounding box so when the bounding box goes, so do the events.
