Drop old stripe shader not needed
update readme
Use new emscripten options to skip unneeded libs

Don't need the in-browser support or the filesystem simulation code.

Fix stuttering audio when in background tabs

Turns out that while timers and requestAnimationFrame are throttled
in background threads, Web Audio callbacks are not! If we are starved
for audio, call into the decoder for more data immediately... and it
works.

Also, fix for total regression on IE/JS (can't use document.contains)
Quick fix for pause regression

Accidentally broke pause when adding the background-tab fix.

Better fix would be to actually halt audio output on pause,
but that's more work. :D
a little shader cleanup
drop an old comment
Code cleanup: FrameSink & WebGLFrameSink

Move some software YCbCr-specific out of OgvPlayer, wrap the
software and GPU output methods in the same API.

Note this means we no longer get separate color & draw times,
which should be fine.
drop now-unused color time from stats
drop colorTime from Flash version as well

merge yuv & drawing time into one to match current JS
Ensure we have a minimal setTimeout when we have a target time
Fix broken delay after ended
Range-based streaming, seeking

Currently may explode if no range support. :)

* StreamFile majorly refactored
* -> supports seeking: https://github.com/brion/ogv.js/issues/123
* -> uses smaller buffer chunks: https://github.com/brion/ogv.js/issues/125
* Basic bisect seek supported for theora, vorbis
* AudioFeeder refactored to support stop/start and seeking
* Audio now shuts down when paused: https://github.com/brion/ogv.js/issues/78

Some issues:
* No fallback for non-Range-handling stuff
* Issues a separate HEAD request to get the content-length;
  ideally this should use the Content-Range but that has to
  be separately whitelisted on the server. Seriously?
* Seek doesn't properly detect all packet timestamps and may
  not always go to right keyframe. Will replace all this with
  liboggz in a bit anyway.
Don't alert() on IE 10/11
