131.0.3

1. thanks to @Pehrsons i think the audio bits are a little tighter. seems the backtraces are cleaner when debugging
2. added hardware decoding capabilities for >10.10 systems on h264 only (vtdecoder)
   -it's possible that vtdecoder will need to be 10.12++ only, but right now sub 10.10 systems cannot use VTdecoder when sandboxing.
   -so i've put in fallback behaviour.

better than nothing. someone out there knows how to fix this, i'm not going to waste my time on the sandboxing issue any further. i got more interesting and other shit to do for the next few days.
