Change how tweets are fetched on Catarse's Homepage #changelog

- You just need to have a div with id "twitter" and a data-username
attribute with the twitter profile you want
- Fix Facebook data-width, now it's not breaking the layout.
- Removed the "ProjectsIndexView" shit. As the script had just 2 lines
of something, we can make it bind automatically.
- Remove last_tweets private method from projects controller (why the
hell this was there in the first place?)
- If you read all these lines, I love you.
