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.
While true, I'd much prefer choosing the more performant method right from the start and then not have to worry about it. This way we only have one listener and one widget regardless of how many machines, containers, or units that are created.
