Renders a simple HTML version of this Objects attributes. Does not render functions. For example. Given this Sammy.Object:  var s = new Sammy.Object({first_name: 'Sammy', last_name: 'Davis Jr.'}); s.toHTML() //=> '<strong>first_name</strong> Sammy<br /><strong>last_name</strong> Davis Jr.<br />'
function() {
      var display = "";
      $.each(this, function(k, v) {
        if (!_isFunction(v)) {
          display += "<strong>" + k + "</strong> " + v + "<br />";
        }
      });
      return display;
    }
