Replaced the clown service airlock with a theatre airlock, added an airlock to the mime room.

About the PR

I replaced the clowns airlock with a theatre airlock, allowing them access to their own room and making them not stuck during round start.

And then I also added an airlock to the mimes room so it's not open to the public.

Why / Balance

Even though it's funny that clowns can't open their doors on shift start I think they deserve at least a bit of love from time to time too, so giving them properly configured warm rooms on glacier is the least I could do.

Technical details

Just a small mapping change in the mapping editor.
