Remove navigation for new page load structure

No longer using jQuery to load content. Using PHP $_GET instead. This is
much more scalable since I'm using AJAX to load/change content. Want
updated content between screens
Use $_GET to load different pages

This is a lot more scalable since using AJAX. Content wouldn't refresh
between screens unless I do a hard reload.
