remove deprecated methods, cleanup idetalk (idetalk must use our built-in web server, will be done in next commits)
I have changed IDETalk xml-rpc server implementation – now it uses built-in server (note: since IDEA 12 XmlRpc server just one of the EP implementations) on custom port (custom port is required because by default we listen only localhost due to security reasons).

IdeaAwareWebServer, IdeaAwareXmlRpcServer and PeerFactory were removed (marked as deprecated since IDEA 12). In case of any problems — you know who is responsible ;)
