Multiplayer + Cleanup update
Features:
- Untested Multiplayer. This isn't my work, simply the unreleased code from andre111. Can't test this.
- Golden Apple. With an Enchanter you can make an apple that restores lots of health.
- Toggle-able god mode. Mostly for me, but I figure people like to cheat, so now you can enable "Beta Features" as well as god mode.
