AbstractConnectionDecorator->__get ()
sorry for being not so familiar with github yet, but idon't know where to announce the following correctly, so i post it here:

In the class /src/Ratchet/AbstractConnectionDecorator.php:
abstract class AbstractConnectionDecorator implements ConnectionInterface{..}
the method "_get()" should check if the property is set:

```
public function __get($name)
{
    if (isset($this->wrappedConn->$name))
    {
        return $this->wrappedConn->$name;
    }
}
```

instead of returning it unproven directly. I noticed Warnings in my Logfile.
Thanks
