Opening the developer overlay doesn't work in games started through the lobby

[leper]

Pressing Alt-D to open the dev overlay doesn't work in games that shouldn't be rated (non-1vs1 games) because the game was automatically configured locally as being rated.

To fix this issue we should first allow the player to enable/disable rating via a checkbox on the game setup screen and eventually make the box auto-disable itself when a game is not ratable.

This is really just that there should be a rated/unrated checkbox on the gamesetup screen. The complexity stems from the box automatically pre-configuring itself based on the ratability of the game in question.

It would be best to start with just adding the box and then working on preconfiguration in a separate ticket.

Added "unranked game" checkbox in multiplayer game setup.
