Rewrite

Begin rewrite using composer, Silex, Twig, and YAML Front Matter.
User auth

Added users with the ability to log in and out.

Users are stored as an array in $app['users'] with the key being the username and the value a bcrypted password.

Moved templates and content into an app directory.
Added a redirect and flash service provider that help with user auth stuff.

Removed old views.
Edit pages

Added the ability for logged in users to edit the page.

YAML Front Matter should be optional, fixed issue where render was failing if front matter was missing.
Remove unused assets

Removed bootstrap files I'm not using to save on some space when deploying
Add page front-end work

Begin adding the ability to add pages. For now I just have the link, form, and JS to make a request.

Add logout link.
Add page

Add the ability to add new pages on the backend. If the file doesn't
exist, it will create the file instead of returning a 404. Allows for
directories too. If the directory doesn't exist, it will create it.
