* fleshing out XMPP entities, adding XmppWriter and XmppSerializer 

having spent the last couple of days wrestling with .NET XmlSerializer
  and trying to get it to do what is required by XMPP (RFC 3920 & 3921)
  this is the preliminary result of that wrestling (you should see the
  other guy!): XmppSerializer allows us to serialize Xmpp stanza (and
  theoretically deserialize [or reify] them), XmppWriter helps avoiding
  various gratuitous crap added in by off-the-shelf XmlSerializer.

  this is currently not used anywhere but the plan is to use it for 
  at least an XMPPBridgeModule.
