fixes subtitles one-behind bug

Subtitles were lagging behind the playing video by one render.
The cause of the bug was that file-member property ReactPlayer::config
would get updated in componentDidUpdate (which happens after render).
The fix was to move the config update step into render

This release includes the lib in repo so that it can be installed via github url
