Map votes should be held at the end of rounds

From the changelog update that added map voting:

Wire updated

•  Map voting system. Once a round has lasted for 5 minutes, an automated map vote will trigger allowing you to vote on the next round's map. By default the vote lasts 2 minutes.
  

•  If you're wondering why this vote isn't at the end of the round, well there's technical reasons as a map switch triggers a full recompile of the game, which takes like 3-5 minutes.
  

3-5 minutes isn't too bad by real life standards, but I think extending pre-round by that long might make things unbearable--consider that some people complain about 5 minute loading times for instance.

I don't know if the 3-5 minute range can be shortened with better hardware. I do know a good part of it due to BYOND code itself; before my time, there was a major BYOND update that drastically reduced compiling time.
