updated added RTMP support. fixes #559

This request takes in https://github.com/videojs/video.js/pull/605 and adds the following:

- updated video-js.swf based on https://github.com/videojs/video-js-swf/pull/27
- change the URL parsing to use '&' as the delimiter.  We've seen this work quite well with Brightcove.  The first '&' seen will be used.  If there is no '&', then the last '/' is used
- add unit tests for the URL parsing changes
