Subject: Add S5BProxyRequest Serializers and Parser

Adds a S5BProxyRequestParser and a S5BProxyRequestSerializer to stroke based on the Swiften classes of the same
name.  These has been missed out previous stroke patches for some reason.

Test-information:

Code inspection against the Swifen classes.

Sanity test ran the unit tests for stroke they still all pass (note I could not
find any unit tests for this class to transfer from Swiften).
