### Update Icons

    // 1. Open http://fontawesome.io/icons/
    // 2. Run this script
    // 3. Convert JSON to PHP Array https://www.google.com/#q=json+to+php+online

    var fa = {
        groups: {
            // 'id': 'Title'
        },

            // 'fa fa-adjust': {'group': 'web-app'},
        }

    var fas = {
        groups: {
            // 'id': 'Title'
        },
        icons: {
            // 'fas fa-adjust': {'group': 'web-app'},
        }
    };

    var $section = jQuery('section#web-application'),
        group;

    do {
        group = {
            id: $section.attr('id'),
            title: $section.find('> h2').text()
        };

        fa.groups[group.id] = group.title;

        $section.find('.fontawesome-icon-list i.fa').each(function(){
            var icon = jQuery(this).attr('class');

            if (fa.icons[icon]) return;

            fa.icons[icon] = {group: group.id};
