The Final Bug?

Getting close to having all the changes on the TODO list. It's been quite a journey so far and I believe the tutorial to be complete now.

- True/False wasn't showing "=" when pressing Different resulted was wrong (red)
- Wrong answers don't auto-skip (no, repeatedly pressing = won't help you cheat)
- Changed the timer from 0.1s to 1s to alleviate the battery drain
- Minor change to the Tutorial (True/False mode stays, no symbols)
