Re: remove snow cheat in build mode

@LadyAofPineapple Yes a toggle is a great idea. Especially since console players can't use most cheats.
Actually it makes sense to just have no snow at at in build mode to cover lots that are always snowy. I've built houses in Mt Komorebi near the slopes before and it's really tricky. I ended up using a raised foundation to include most of the exterior to see what I was building. In particular it's really difficult to place landscaping as shrubs/trees/flowers immediately revert to twigs in a winter state.
