Modifying control bar API to be located in MediaPlayer.js for time, duration and seek etc.  added utils for basic player development into MediaPlayer.js.
Adding type and removing hardcoded video as type to make sure this works when video is not available and is audio only.
Removed unneeded comments and added simple date and time formatting to to the formatUTC method.
Ran grunt and added DVRInfo.js in Dash IF Player Index page.
