have a map rotation

[Vitatroll]

Cog is superior to the other maps by far. The only reason to go back to the old maps is for nostalgia, and the only map currently retrofitted to do that is Donut2. Heck, it would probably need to be re-refitted since it was last seen in october(?).

I could see this as a monthly or bimonthly day-long thing, but making it semanal would be a bit too much for my tastes.
