Title: INT-2489: Added support for empty temporaryFilePrefix

modified AbstractRemoteFileOutboundGateway to work without creating a temp file with a ".writing" prefix for an edge case in which file rename permissions are not set. If you set the tempFilePrefix to null, " ", or "", the initializer will set it to an empty string. This will create a "temp" file with the original file name and circumvent renaming the temp file.
