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.
I'd like to disagree to a point here. The scalable issue would be the render() call which can wait until hover.

I'm not sure there's any issue creating the instance as it should be extremely cheap.

If we have performance issues let's hash that out in a real scenario. We should be able to test with a TON of unplaced units and get values well enough.
