Subject: Only calculate S5B candidates if supported by recipient

As per swiften patch of the same name
(e9ed818dac91e280eb8da86dc8494710f1da0624), some changes to
FileTransferMangerImpl on how it creates an Outgoing File Transfer.
Also added a copy constructor to FileTransferOption that had been in
swiften but was not yet implemented in stroke.

Change-Id: I314ac5ef7f8e082c7121ad89c012b84569f98d6c
Test-information: Unit tests still pass.
