Reorganize the stylesheets
Only signed in users are shown the navigation list

This is mostly because I'm also including the logo in the navigation bar, so I

home link, which redirects to the login page, and a link to said login page.
Quite pointless!

Submit buttons are automatically colored blue

Proper blue as defined by the .button class.
