YAWoFFA updated to 0.8

A small update with some great improvements.

• Major scoring overhaul. I think it is now more fun to play. Check out the included .readme for more info.
• Changed cost for buying vowel from 500 to 1000
• Added a RESET POT to the wheel. Land on this to reset the pot to starting value.
• Submitting a solve is now more forgiving. You can omit special characters from the entered answer. Only A-Z and 0-9 is required.
