Mafia: /targetlog, Standby Recharge fix

Fixing a rather rare error with standby recharge.

And adding /targetlog, because Fuzzy:
(21:09) RiceKirby: targetlog was really easy to code
(21:09) Fuzzy: i cant even make cereal and milk without starting a fire

Also adding a public message for when games end so people can make mafia games-related Client Scripts.
