[support] Views filter rooms by occupacy

[Lluís Forns]

I was trying to make it without coding a new module; the steps and the
result are:

1. created a join, which is no required
I can list all the rooms with the nid of bookings (if avaliable).
2. Created a filter per dates:
only rooms with bookings for that night are available
3. Filter for NULL related booking nid
No room listed

I think the filter should affect only joined content, but it it is
affecting the full content. How can I limit to the join?
