Subject: [PATCH 06/14] WebRTC.MediaHandler: split stunServers into separate
 objects

This avoids the following sort of situation, which Firefox (as of 33.0.2) has
trouble with:

  var RTCPeerConnection =
    window.webkitRTCPeerConnection || window.mozRTCPeerConnection;

  new RTCPeerConnection({
      'iceServers': [{
          "url": ["stun:stun.l.google.com", "stun:stun2.l.google.com"]
      }]
  })

addresses #117

Subject: [PATCH 08/14] Syntax sugar for rendering media.

ua.invite and session.accept can both be passed an
HTMLMediaElement (audio or video) in lieu of options.
Remote media will render to that element, and constraints
will be inferred from the type of element (audio only for audio,
audio-video for video).

Example:

new SIP.UA().invite('welcome@onsip.com', document.getElementsByTagName('audio')[0]);
