Updated a few GS servers to promote ocn mapmakers

I reworked on some GS rotations by removing some of the maps by Vechs and adding maps by regular ocn map developpers to promote them.
Also, the maps I added are: GS: Whirlpool, GS: Blocks, GS: Fairyland and GS: After The War. I added these maps because people seemed to like them.

Feel free to ask me if I should add or remove some of these maps from this pull request.
