High Scores Reset, Etc.

[Kyzrati]

I just reset the high scores--the new board will be the last one for Alpha 3c, and the last one of its kind.

Following Alpha 4 I'll be upgrading the system to add more data from each run, and also rank runs separately based on efficiency, which will allow stealth/speed runs to be represented on their own and compete based on their merits rather than score alone.
