1. Added number keys 0-9, -,= and numpad keys 0-9,-,+ to select squares. Square selection starts with 1 and goes to 9, 0 selects square 10, - selects 11 and =/+ selects 12.
2. Added Undo last move button. Shortcut key is CTRL Z or CMD Z. Undo will clear the bookmark.
3. Shortcut keys work only when the mouse cursor is in the playing area, i.e. in the squares. This is to prevent misclicks.
4. Win condition now checks for colour matches that do not necessarily correspond to their original position.
5. On winning, the player will not get a confirmation popup on pressing 'New Game'.
6. Hid the Stats button. (Will be releasing Steam integration in the future)
7. Theme names are now translated.
8. Fixed a typo in 'Goto Start'.
