Couchbase agent changelog

When sourcing data from Couchbase the snapshot might fail to complete correctly in certain cases;

Fixed an issue that could cause the agent to popup an error message when the target scope/collection is empty or it does not exist even if the agent was actually creating it successfully.

Fixed an issue that could force the user to manually define target fields within the Fields editor tab in conjunction with an empty collection due to existing Sync Gateway reserved documents.

Fixed Couchbase information schema when collection is empty.

Fixed wrong map and array values mapping when Couchbase is used as a source agent.

Added use of INFER to discover documents data structure to avoid needs of index.

Added number data type support.

Added upsert fallback on insert error
