Thanks eXish for size change feature for TP

- fix tp typo

Thanks to Quinn for the following update:
- Add maze size mod setting (2-26)
- Add autosolver
- General code cleanup

Makes it so you can move while the sound is playing without any issues.

Build 1.7 Notes:
- Fix indexOutOfRangeException when you attempt to press the center button while sounds are playing already.

Build 1.6.1 Notes:
- Fix bug where the exit was all the way over...
- Added a logging line to show where the maze ends so repo contributors don't have to remake that Echo LFA code over and over.

...to the middle of nowhere.

Build 1.6 Notes:
MAJOR CHANGE
- The maze is now 4x4.
- Changed the code so the mazes are actually random, and so it can deal with any maze size.
