Mahjong! v4

In this version;

• Added saving and loading, you can now pause and resume the same puzzle over multiple sessions, simply Pause and quit to Main Menu to save game automatically, If you have a game in progress you can resume it via the Continue button.
• Added a level select screen (accessible via New Game) showing a preview of the layout, the layout name, difficulty and your best time.
• Added a best times screen, this is a summary of your best time per layout and works better as a place to reset your times with Z+X than the old Game Over screen.
• Added new Shuffle and Hint icons to the game screen, now represented by crossed arrows and a magnifying glass.
• Added 9 new layouts bringing the game to 24. This is split into 10 Easy, 10 Normal and 4 Hard layouts.

This should be the last major update to the game unless anyone spots bugs or it suddenly gets popular :D
