Started some more work on XML-RPC.Net, implementing the fault code interop spec. This will be in v0.2.2 - I'll back out some of the async call related changes in 0.2.1 to get things working again.

Ran the XML-RPC.Net interop test client:. Apart from unimplemented methods the only problem seems to be XMLRPC:Lite failing echoString when passed an empty string.
