* Added a dropdown to video & audio settings
* Changes to ListHelper:
** Limits resolution when code requests the default video resolution
** Limits audio bitrate when code requests the default audio bitrate
** Removed some dead code and did some cleanup
** Make methods private/protected to help understand what was in use
** The code now chooses one format over an other using a simple raking system defined in array constants. I realized I needed to do this in order to choose the most efficient video stream. I did my best to evaluate the video and audio formats based on quality and efficiency. It's not an exact science.
** Made changes to the tests to support my changes
