Multiplayer Resurrection!

Multiplayer is back.

For all 6 of you who play, you may have noticed that multiplayer has been offline for a few weeks. The infrastructure provider I was using changed their pay structure, so I've been in the process of moving the backend to a more reliable long term solution. Rejoice, for multiplayer should never be down again!

- Moved the backend to more reliable long term infrastructure

- Fixed two small bugs with multiplayer
