popcornjs.org demo video broken

[minshallj]

After the commit that removed twitter was merged (#332), the popcornjs.org demo video has been broken. At 29 seconds (Will Ferrell dancing) all content stops appearing next to the video. Google developer tools report this error:

Uncaught TypeError: Popcorn(...).listen(...).footnote(...).footnote(...).image(...).googlemap(...).googlemap(...).flickr(...).twitter is not a function

I don't really know anything about popcornjs, but wherever the twitter stuff went should be included along with http://popcornjs.org/code/dist/popcorn-complete.js on line 158 in the source for popcornjs.org
