Make force game rebindable (and unbindable)

[ZellSF]

Whenever I switch chat modes I end up forcing the game, this gets really annoying, really fast.

As a work-around you could rebind the chat mode button.

But yeah, work-arounds suck.

You can use Lua to do that.

Uh? All I can find in changelog says a command for binding forcing games, but it doesn't allow you to unbind the default keys.
