Moved BasicAuthTransport to rtorrent/lib/xmlrpc/basic_auth
Added xmlrpc scgi support
Inserted request() from Python 2.7 xmlrpclib.Transport into SCGITransport to fix Python 2.6 specific issues with xmlrpclib.Transport
Fix to SCGITransport.single_request call to socket.getaddrinfo with a long type port.
rpc_methods are now updated after a group is created, should fix MethodError exceptions when calling group methods.
Merge branch 'develop'
