#2 patch to fix exception handling in marquee-xmlrpc

[Jesus M. Rodriguez]

Created proper data encapsulation within the
XmlRpcException class.
Enhanced the writeError method to return an errorcode
and a message to the client.

The previous release had a hard coded -1 as the error
code which is not ideal. The above patch will allow a
developer to send back proper error codes for custom
exceptions.
