Merge pull request #128 from doopl/master

Disable animations between chooser and gameplay screens
Fix #126: undo/redo on action bar was totally broken, and broke Type as a side-effect.
Move Settings back to Game menu, and absent on chooser, pending a better place to put it there.

The trouble with hiding Load in overflow, and with overflows generally, is people are still releasing phones with a Menu button where you then don't get the overflow dots, so there's no obvious hint to press it (Fairphone).
Reinstate settings icon from action bar icons pack.
WIP: new game icon. Dots need to be made transparent for icon conversion.
New 'New game' icon
