No more ugly pretending to be chat messages.
Eject idle commanders, and show all talk state

- Commanders that are AFK for longer than "CommanderTime" minutes are
ejected and banned from commanding for the rest of the map.
- All talk state is shown at the bottom of the screen before the game
has started if AllTalkPreGame is set to true.
- Prettified some more messages I missed.
