Add debugging helper and FileTransferTest.

FileTransferTests tests file-transfer interoperability with Swiften itself. It can test all combinations of FileTransferOptions or a specific combination when given. Test-Information: Inspected XML logs to ensure it does what it is supposed to do. Change-Id: I06215b60419dd23b367d01a2f038245a6c977720
