getUserMedia fall callback

[aykutyaman]

I think getUserMedia fail callback must be called with error:

getUserMedia.call(navigator, options, function(stream) {

        rtc.streams.push(stream);
        rtc.initializedStreams++;
        onSuccess(stream);
        if (rtc.initializedStreams === rtc.numStreams) {
          rtc.fire('ready');
        }
      }, function(error) { //here
        alert("Could not connect stream.");
        onFail(error); // and here
      });
