It should be possible to use the existing cheats in autostarted games.
But for the following reasons, it is not needed to add a command line option and just enabling them always is needed:
- For consistency with gamesetup.js, as this page always enables cheats in SP
- Since the autostart multiplayer gamemode has never implemented player assignments and must have relied on the change-perspective developer feature
to control players from the observermode, which was restricted to cheats being enabled as of rP17170.
While at it, fix that example map which doesn't exist since numerous years.
