Added the ability to limit video quality if using mobile data.
* 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
