Merge pull request #121 from vkorapaty/feature/bookmarks

Made endpoints and methods into links.
Setup 'config.rb' for Compass use. Modifying the Sass file will be easier with Compass available.
Updated 'style.scss' to generate the current style.css file correctly.
Adding support for request bodies for PUT and POST methods, and nested
parameters for PUT / POST method request bodies.

Functionality description:
This patch adds support for documenting parameters of a request body. As
values are filled into the content parameters, the method's text area is
filled in with what the request body should be. The text area is what
will be submitted as the request body, and can be modified directly if a
user wants to.

Implementation details:
Content parameters use nested lists instead of tables. It was easier to
figure out how to style nested lists compared to styling nested tables.
Styling was done using Sass and Compass, making use of the updated
style.scss.

In app.js, the 'requestBody' variable has been replaced by the 'content'
variable.
Adding an example API and updating the README.

Adding content_parameters_example.json to demonstrate how the content
parameters work. A first-pass has been taken at documenting the new
functionality in the README.
Recompiled stylesheet and fixed a minor error in the content parameters example.
