Cleaned up and updated a lot of code:

Libraries:
Added FontAwesome for the icons (instead of using Bootstrap's icons)
Added Google Visualization API file (only for code completion)
Added jQuery 1.9.1 file

Assets:
Changed the logo
Changed css.css to base.css
Changed add_competency.js and add_role.js, changed Javascript to jQuery
Added base.js

Controllers:
Added view_feedback_overview, which displays a list of all the reviews you can do (this also means you can review yourself now)
Added some validation to various files (more to come)
Added a way to add a title to the page: set('title', $title). This has been added to some files already.

Changed $smarty->display($template) to return html($smarty->fetch($template))

Views:
Changed the structure of the application. Every template gets returned to the main layout.tpl, which also has the header,
the menu and the footer.

Changed random values for self in the report to actual values from the database
Combined the edit and create template for every type into one template
Changed the drop-down list in edit and create user so roles get filtered based on the selected department

Added show comparisons checkbox in report, so it only shows the rows where both the average and self are present
