Subject: * adding XmppPresenceStanza and deserialization/reification support

  having reached the intermediate level of .NET's XmlSudoku, i've
  now figured out how to do deserialization using different 
  XmlSerializers (this stuff begins to grow on me, sigh).

  [still not used code, work-in-progress]

* adding convenience property on OSHttpRequest.cs (from awebb)
