This script enables wiki editors to create anchor tags with the class "time-link"
that will be parsed for seeking to specific time stamps in the main video on a page.
The tag should look like this:
<a href="#mainVideo" class="time-link">mm:ss</a>
This could be extended to accept hours in the time stamp as well, but currently does not.
