Inline WebVTT Styling

Adds the ability to embed CSS style sheets within the STYLE block of a WebVTT file. This feature is supported by several other web browsers and video players including Safari and VLC but not Chrome.

To ensure a consistent experience across platforms, Chrome should conform to the WebVTT specification by supporting inline styling. This project is part of a larger effort to improve Accessibility around the Media Experience in Chrome.
