Missing handlers for `webrtcup`, `media`, `hangup`

[vogdb]

I've checked. When hangup is received janus connection does not break, session does not destroy, plugin does not detach. Seems it is only about having media stream?

[vogdb]

Verified. Media breaks and we need to reconnect to room/mountpoint.

Now I think that we can even ignore those events. If use needs those events, he can do this:

plugin.on('message', function(message){
  switch (message['janus']) {
    case 'webrtcup':
    case 'hangup':
    case 'media':
      //do whatever you want.
      break;
  }
})

@zazabe your thoughts?

[vogdb]

well, here are the changes. @zazabe please reject/confirm them. I'm still unsure about having them. btw the original janus.js does not have callbacks for those events https://janus.conf.meetecho.com/docs/JS.html

@zazabe wdyt?

[zazabe]

I think only hangup is useful as an event, others could be catch by listening on message as you said.

@zazabe please review
