LOBBY OBJECT

uid: uid,
name: string
owneruid: useruid,

NOTES
- Users can only own one lobby
- Lobby UID is "join code", will be much shorter than userid
- When inactive will be deleted, unlike users
- It's a waste of memory to store the name along with the useruid, however
i believe it will save complexity in the domain logic
