Server-side in-progress games

[0spooky]

Often, games are lost by people refreshing their devices, or they would like to switch recording players, or they would like to see in-progress games. We can solve all of these issues by recording games server-side and letting users view data from there.

Required qualities:

1. Games must not be stored indefinitely, they should be purged at some point either late at night or after some holding period.
2. Games should have some viewing method for non-players
3. Games should have some edit enabling method for players
