For map votes, add a delay of at least two different maps (including variations) to prevent the server mostly playing on the same.

I notice that especially on All Map servers people would often vote for the same map over and over.
The result of this is that we stuck on Tunnels e.g. for three maps in a row, which gets easily boring.

The pool of available maps isn't huge as of now, but please, change the voting at the end of a round so we don't end up playing the same map again, or a variation of it.
