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 approach won't be scalable if there are hundreds/thousands of machines.
A scalable approach would be: 
- Have each token have a vertical "..." which is only visible when the user hovers over it.
- The machine view container would have a delegate on it's container waiting for clicks on this "..." button.
- On click it would instantiate and render a more menu widget and position it with the token.
  - This will allow us to easily make sure only one is ever rendered at a time as well.
