Map rotation/voting and gamemode rotation/voting

I think the map rotation and voting system has to be tweak.
We all know we can't play a map 3 time in a row in the same lobby.

Make it that when we've played a map twice in a row that the previous map vote will become a next map also. So we can choose between 2 maps and a random map.

The gamemode rotation/voting. I play groundwar again for a couple of days. And it happend's a lot that the votes are for the same gamemode. Make it so that you always can choose between 2 game modes.

And also always 2 different maps. It also happend's that you can choose same map but different modes.

Edit: The gamemode voting is also for multi-team and moshpit
