Checks whether the sidebar title has wrapped to the second line. If so,
decreases the font-size of both sidebar and navbar titles.
function setTitleSize() {
        var sb = templateOpts.sidebar.enabled;
        var nb = templateOpts.navbar.enabled;
        if (!sb && !nb) return;
        var $a = sb
            ? $('.sidebar-title a')
            : $('.navbar-title a');
        // titles font-size is 18px
        if ($a.height() > 18) {
            var css = { 'font-size': '16px' };
            $a.parent().css(css);
            if (nb) {
                $('.navbar-title').css(css);
            }
        }
