Hosted game is invisible while host is viewing the CnCNet lobby

(Bug report from Dawn of the Tiberium Age staff)

When someone is hosting a game, and they switch to the CnCNet Lobby via the top bar, they stop sending game broadcast messages, making their game room invisible to other players until they use the top bar to switch back to the game room.

A fix would be writing a new Timer class and adding Timer support to the WindowManager, and letting the timer handle game broadcasting instead of CnCNetGameLobby handling it in its own Update() method.

Confirmed to be fixed.
