Youtube thumbs

This branch started as a heroku scheduler but then I got the request to add the YoutubeThumbs so I kinda switched gears on my topic mid branch... sorry

So this branch added a migration and new fields. This might need you to rebundle and run the migration before it will open. it will also prob ask you to comment out the checkin fields on the index page until the first run through on your local because you wont have the fields for the up and down teaser. 

Disregard the clock files in the lib etc for now, that will be the next branch
