[Qol] Lobby option to switch to a black screen/different background

[xqzpop7]

I would love it if someone added a simple toggle between the normal random lobby image and a black screen/another image.

I don't know much about Byond's limitations, sorry if this is a stupid request.

As for why I'm asking? It would help if you don't live alone and don't trust your roommates to search through your open windows while you go drink water.

Thank you so much if you decide to implement this.
