record times when a user connects to and disconnects from the lobby in the database

[alicexigao]

right now, only the last time the user connects to the lobby is recorded. To allow us to compensate people if they wait in the lobby for too long, it would be ideal to use a separate table in the database to record all the timestamps for when a user connects to the lobby and when a user disconnects from the lobby.

We can't record every connect and disconnect from the lobby (without changing the schema significantly), but we can definitely associate one connect time with a session. Would it be better to keep the earliest or the most recent lobby time? Probably earliest, if you want to measure how long they had to wait in total?
