More granular system for controlling whether a game is rated or not

[Jazcash]

The following functionality has been requested:

• Allow players to make a match unrated if they wish
• Certain match settings and modoptions should not allow a match to be rated, and must be easily configurable by devs
• Display whether a match will be rated in the lobby, before the game starts

We now have the is_ranked SPADS battle setting, that players can change to 0 to make the game unranked. It's 1 by default, thus, all games are ranked by default.

Ideally, a list of modoptions should be configurable on the server. Any game with at least 1 of these modoptions enabled should have its is_ranked modoption changed to 0. If players try to manually change this value back while any of these modoptions are enabled, (i.e. !bset ranked_game 1), then the server should either block this command, or otherwise force ranked_game back to 0 immediately after, and a message should be shown to players, e.g. The following modoptions must be disabled for the game to be ratable: disable_fogofwar, norush.

Does this sound feasible/sensible for implementing into Teiserver?
