Document Query deduplication

Users are frequently confused why count() does not return the same
number as the number of objects returned by all().  While we continue
to want to find a better solution to this problem, in the meantime
this has never been clearly documented.  Add an FAQ section with
links from .count() , .all(), ORM tutorial.
