Random maps
Now, instead of random S maps, XL maps will be generated in the game, instead of M - 180 x 180, instead of L - 216 x 216, instead of XL - 252 x 252.
By default, regular M maps are generated. I will fix it later to L, as M maps are not played anyway.

Map editor
Instead of 36 x 36, it creates 144 x 144, instead of 72 x 72 - 180 x 180, etc.

I fixed everything except the frame size (for extra-large maps, the dotted frame size is the same as for XL).
