(svn r2298) - CodeChange: removed CmdAbuses: CmdSetTownNameType(), CmdStartNewGame(), CmdCreateScenario(), CmdSetNewLandscapeType() and CmdGenRandomNewGame().

- CodeChange: renamed CmdTrainGotoDepot() to CmdSendTrainToDepot() to be consistent with other depot commands.
- CodeChange: 'newgame' console command now calls the unabused GenRandomNewGame(). For the server it still creates a new game, a client quits the game and continues in SP.
- CodeChange: in the game-difficulty window, setup the disabled buttons on window creation, not every redraw.
