Optimize AJAX modals calls
Updated AJAX modal calls:

-Now making separate calls to the loadLinks function for each modal element.
-Also the loadLinks function now checks if modal was meant to load an external page and if it does then it attaches the click event handler.
Updated AJAX modal calls - Removed loadLinks function:

-I removed the encasing function since the function only worked on the Foundation modals and there is no need to programmatically call the "load" method. Reverse this commit if you ever need that functionality back.
Removed AJAX loading function:

-Foundation already has a built in way to load modals with AJAX. I removed the custom code from app.js and added data-reveal-ajax="true" to each modal element in the HTML page.
Update to the previous commit:

This commit actually contains the HTML changes as stated in the previous commit which was adding data-reveal-ajax="true" to all of the reveal modals.
