[support] Views filter rooms by occupacy

[Lluís Forns]

Not working; nearly solved this using:
[other filters]
AND
[
filter_start_date > booking_end_date
OR
filter_end_date<booking_start_date
OR
booking_nid IS NULL
]

But nearly all rooms appear because they have previous bookings outside the
interval.
