Incorrect QueueRunnerThread implementation

[th0br0]

The current QueueRunnerThread implementation returns a handler to the future upon creation.

However, this handler is not being passed an instance of the HandlerThread's looper!
The looper is only available once HandlerThread.onLooperPrepared has been called.

class QueueRunnerThread
  extends HandlerThread( this.toString )
{
  override def onLooperPrepared() = {
    threadHandlerFut.succeed( new Handler(getLooper()) )
  }
}

I believe this is now fixed on master... let me know if it still looks off. Thanks!
