Resolve "Add creation/update ops for roombookings"
Only wrinkle with this is that the room bookings get created in TermTime with a "pending" status (even if a state = 0
is passed to the API). Spun off #30 (closed) to investigate/chase with Semestry.
Also, added a cap
(capacity) with a placeholder value of 1 for creating/comparing these bookings. Actual figure is probably not needed and Bookers ExpectedAttendees
seems unreliable. Anyway, putting in a value to the bookings are considered valid in TermTime. i.e. going in to edit them in the UI does flag the field as missing!
Closes #12 (closed)
