Twitter Bootstrap support

Began working on a landing page and thought using the Twitter Bootstrap framework would be a good option. The build page could be cleaned up to use the same framework. It's a responsive design and the javascript has a lot of nice elements for toggles, popovers, etc to make Feed2JS a modern web app. Because this would be a significant shift I moved this to its own branch (and ok, I wanted to learn more about how branches work) so if you don't want to merge this back into the master codebase and keep it in a branch thats fine by me. I'll most likely be integrating this into the EC2 AMI so that it's clear when someone fires one up and goes to the domain what the next steps are.
