Add jPlayer 2.7.1 patch to fix mp3s not playing on Android OS.

Add the minified jquery.jplayer.js to VWF.

Modify vwf.js to point to 2.7.1 version of jPlayer.

Note: this jPlayer release fixes mp3 audio playback, but does not fix mp4 video playback on Android.

Please review.  @scottnc27603 @eric79
