Vinnie Falco 765cb22b48 Invoke callback on pings and pongs (API Change): ...

fix #248

callers to more efficiently detect when a connection is still lively:

* pong_callback renamed to ping_callback
* Callback signature has an extra `bool` to indicate if the received
  control frame is a ping or pong.
