Usability changes
-Added glyphicons for all expandable elements.
-Accordions get a chevron down icon that appears upon hovering the element.
-Projects get a folder icon that opens when clicking on it.
 The logic for opening and closing icons has several triggers and is a bit complex as a result.
 Whenever a project is open, it needs to close when transitioning to another page.
-It was necessairy to change some of the logic for opening projects from the main page. The links to projects from the media boxes now indicate the array order of the project in the project page.
