Add option to hide table from lobby?

[nemec]

When you create a game it lists "Play Permission" and "Observe Permission". I was wondering if it would be possible to add "Lobby Permission"? If selected the players without permission wouldn't even see the table listed in the lobby. This would clean the lobby up significantly for users who use this feature.

Player can use the Filter button to hide "private" tables, which include tables they don't have permission to play on.
