Setup backbone router, create Post backbone views, create Post templates

The index page now serves Posts dynamically. I have blocked out the Post's votes, date, image, and company for the SGM since they are still being worked on.
To see how this works, make a new Post and refresh the index page.

"@user = User.where(:id => 1).first"
"@user.posts.create(:title => "This is the Title.", :content => "This is the content")"
