Merge branch 'msimons/master'

# By Marco Simons

* msimons/master:
  - minor changes to make jdbc-river work on 0.21 branch instead of 0.90 - Changed the acknowledgement of bulk request in inserts instead of updates. ( with no update on river source table to avoid deadlocks)
  Support for elastic search 0.21.Beta1-Snapshot including partial document updates via Bulk API
  Support for Oracle XMLDB XMLType column with proper stream closing.
  When acknowledgement  is used in a table strategy the main river source_operation for each item is updated to 'ack' To prevent connection locks in this scenario we are using the same connection. (writeConnection)
