[implemented] UPDATE to latest Exoplayer (android/firetv) --Listen to your customers--

PLEASE update android/firetv apps to latest exoplayer! Many issues including subtitles would be resolved and comes with many core improvements. Last core update was a long time ago. Same complaints keep coming up which are all resolved by latest exoplayer versions or switching to something much better eg MXPlayer, MPV, BSPlayer, VLC.
