Version 0.7 - Twice as fun

Big change this time around is the addition of a smaller box to pack animals into! It makes for a quicker game I think, although once you get to the elephant there's not much chance of continuing for much longer.

Need to decide whether to have both play areas in the final game, or just one.  

• Added additional small box play area, so we now have two game modes, large box, and small box
• Added pause screen.
• Added a small in game logo
• Did some work on possible keyboard/controller support.
• Also added silent wolf addon for high score tracking (not implemented yet)
