Added missing rule for even squares.

@digital_lighting I've embarassingly managed to forget listing the intended even square rule, but it can be solved without it.
It's perhaps best to remove those squares, but I'm cosmetically attached. I think I'll just add the intended rule.

Bit better than the first.

Not sure if it absolutely mandatory to make the assumption that the squares must be an even digit (as is the standard) but i couldn't see a way to resolve this without this assumption. @scottgarner, can you comment on this?
