Create a widget for video lists

Should be able to list out videos from a playlist or a collection of playlists.

Should look something like this:

<div class="eclipsefdn-video-list" data-show="10" data-paginate="true" data-playlist-ids="A89fbV4xF, MnFu2WxL4">
</div>

This widget is meant to match the implementation of the video_list shortcode. See here.
