Check-ins

[MaxwellBo]

• Push notifications (get the server to to trigger a "Hello World" notification - don't care whether it's Push or Pull)
• Add checked_in_at and on_break_at fields to the User object. These should be some sort of date-time type (obviously going to be datetime in Python, don't know what it is for SQLAlchemy / Postgres. These fields are also nullable (they can be assigned None`)
• Add Check In and On Break buttons OR checkboxes on the Who's Free page, that POST to a /status endpoint. (Try and simulate how /settings works with the state sync exchange)

{ "atUni":  True}

"Hey, I'm actually at uni!" The backend logs the day they logged in at, so the backend knows not to say that they're at uni the following day. This should override incognito mode.

{ "atUni":  False}

"Remove the logged date from the database. I don't want to explicitly say that I'm really at uni, but my timetable will say that I am."

{ "onBreak": True }

"Put me at the top of the "Who's Free" list. Send a push notification to all my friends saying "X is on a break!"
