Removed some unnecessary HTML elements.
Added "alt" tags to the images in these sub pages.
Rolled back to jQuery 1.x. Realized that I'm loading a bunch of IE8 polyfills, so I probably still need to support it in jQuery.
Added a test for fontface in Modernizr (used in the CSS).
Added an alt tag to the course screenshot.
Hide classes taught on mobile.
Source code clean-up.
Standardized data display.
Fixed the load_all_courses method to actually work.
