Multiplayer Patches!

Desync Fixes Some new approaches to reigning in the gamestate in the long run. I had been previously trying to prevent floating-point math based desync. That never really worked that well.

fixedDesync FixesThese three sytems effectively force the host's version of the game onto all the clients whenever they fail a test. This will cause a little bit of rubber-banding - cities uncapturing themselves, etc, but it stops the game from drifting into a crazy desynced end state.

addedRejoin FixesAn old and annoying bug was that starting a new game after exiting an old one sometimes caused a white screen. Shutting down the connection between attempts worked for some people, but not others.

Tracked down some stale static data and references that were screwing up the game-scene entry point after a reload

"RESTART" Command

One commonly requested feature was the ability to relaunch a multiplayer lobby with the same folks, without having to quit to menu and retype in all the codes. I never added this because of the above bug making it necessary to purge sessions. Now it works! The host just types in "RESTART" in the pause menu to start a new multiplayer session with all still-connected clients.

Thanks for putting up with my crappy multiplayer code guys, please report bugs to the discord
