GameMode/Rules/WaitForPlayers.cs

Component used in the game mode state machine that waits for enough players before transitioning. It listens for EnterStateEvent and UpdateStateEvent; on update it checks current player count and moves to the next state when MinPlayerCount is reached. It also contains a timed hack that resets states with DefaultDuration == 999 every 500 seconds using a TimeSince counter.
