client now propagates event when remote is received

As reported on [#1](https://github.com/llevkin/dnode-spider/issues/1) 

server.on( "connection" ) was never fired when trying out the example.

My solution was to make Client an emitter and propagate the remote once it is received.


I'm obviously not sure if that was the place you intended to have this event happening, perhaps it shall come from the "proto" object you instantiated.

Let me know.
