Moved some variables from Gametype to GametypeInfo (Gametype exists only on the Server while GametypeInfo is synchronized)
Created a new HUD-element, GametypeStatus, based on GametypeInfo (the same effect was formerly achieved by using a hack in Spectator and a TextOverlay)
HumanController creates a HUD (additionally to the SpaceShips HUD) which includes GametypeStatus and ChatOverlay and even more in the future
