I did a major rewrite of the layout code, today, and it broke EVERYTHING!!! All "Yesterday's Solutions" are no longer valid for today, and all puzzles have been re-generated.

The reason is so that the layouts can be expanded to MANY more puzzle types.

Previously the Layout format was 8-characters, meaning you have up to 62 different puzzle types (A-Z, a-z, 0-9)
Although I'm not 100% sure I'll ever reach that limit, I figured it was probably a good idea to bump that number a little, since I'm already up to 18 games in the script.

The new format uses two characters per puzzle, so aA, aB, aC, through to z9, then Aa to Z9, and then 00 up to 99.
In all, that opens up the possibility of over 3,000 different puzzle types. ... And the biggest puzzle will be trying to fill even 1% of that!!

But.. Yeah, space!!

Since everything's already broken, I figured I might as well reset the random number generator and give it a bit of a tweak in the hope that it might be a little more random. Time will tell, I suppose.
Hopefully everything works fine. Let me know if you spot any bugs.
