DATACOUCH-28 - Remove explicit setting of setIncludeDocs on View queries.

Instead of always setting includeDocs to true for all View queries, it is now
the assumption that the programmer will enable this if they desire documents
to be returned on their query. The reasoning is to allow for an optimisation
when performing queries so that documents are not returned unless asked for.
This increases performance and reduces payload size in the communication from
Couchbase to the client.
