Added error to write

[Tobbeman]

This error can be used to detect if the connection was broken,
for example if the server goes down between client sending data.

psuedo code:
reply, err := s.exec()
if err != nil {
if err.Error() == netconf.BrokenConnectionError {
retry()
}
}

In my current use case I need to know if the server goes down, since the client will be living a long time, connection between server and client can at some point go down. This fix will let me detect that.

Yes this should be error checked. Good catch.

@nemith
Can you take another look?

Thanks for fixing this and sorry for the long review time. I guess no one else is really maintaining this package.
