Merge DM-DM_deployment to HEAD

18665 : Switch over to using new surf <formdata multipart-processing="false" /> configuration option.
   - now the PostContentCommandProcessor and PostSnapshotCommandProcessor handle their own MimePart processing.
  18683 : SAIL-288 Implementation of TransferService client side cancelAsync.
  18716 : Adding TransferEventBegin missed from asyncCancel work.
  18734 : Transfer format : implementation of null properties and Serialized base64 Java objects for type d:any
  18749 : SAIL-290: Added features that provide asynchronous commit on the receiver end and the ability to query commit status, as well as code that writes a progress report on the server side (currently only plain text) and the functionality to allow a transfer to be cancelled
  18750 : New files that should have been checked in with previous commit but weren't...
  18770 : Various transfer service work.
   - correction to transfer report name.
   - use surf Base64 Encoder
   - implementation of async commit to the TransferServiceImpl
   - implementation of the statusCommand through the HttpClientTransmitter.
  18773 : transferId was null.
  18780 : Changed the server-side commit to occur asynchronously.
	Added two test actions to transfer a single node or a tree of nodes.
	Tweaked TransferDefinition to provide varargs version of setNodes.
  18793 : SAIL-290:    Added a couple of test actions.
    	Added varargs versions of transfer and transferAsync on TransferService.
  18794 : SAIL-290: Added "targetExists" operation to the TransferService interface.
  18804 : SAIL-36: Fixed an issue where transfer could fail if numerous nodes with the same cm:name value are transferred.
  18805 : SAIL-36: Added model file that should have been with last commit.
  18808 Continuing work on transfer report.
  18825 TransferServiceImplTest green line.
  18836 : Added a little more output to the server-side transfer report. 
  18848 : More work on transfer report.
