I've just renamed Adv3 to Probuilder.

It is still and advbuilder map, but it is also for probuilders to build in to try for advanced builder rank.

I'm sure most ops already knew that, i'm not sure if everyone did though, and i'm just putting it out there. So just remember to remind all new probuilders to builder in the probuilder map, not that we have very many probuilders.

And yes, I do know that MattSky is a probuilder, I've already let them know to build in the map.

Kthanx.
