MazeFinger feature update and improvements

Hello Everyone,

Due to popular demand, certain feature requests have been added to MazeFinger in order to improve your gaming experience. At ngmoco:) we take our games very seriously, even our free ones!

The following features have been added to the update:

- Hardware silent switch is respected by the game now
- High scores now save dynamically and will be preserved if you choose to leave the game early
- Game state is preserved on interruption (phone, text, or home button)
- Miscellaneous optimization

The update has been submitted to the App store and will be available soon. We'll make an announcement when the update goes live.
