Support goog.inherits

/**
 * This creates a TwoThumbSlider object.
 * @param {goog.dom.DomHelper=} opt_domHelper Optional DOM helper.
 * @constructor
 * @extends {goog.ui.SliderBase}
 */
goog.ui.TwoThumbSlider = function(opt_domHelper) {
  goog.ui.SliderBase.call(this, opt_domHelper);
};
goog.inherits(goog.ui.TwoThumbSlider, goog.ui.SliderBase);
goog.tagUnsealableClass(goog.ui.TwoThumbSlider);

results in a class definition for TwoThumbSlider without the decorate method that comes from SliderBase.

But that's correct, isn't it? decorate is a method on the parent class, after all. Isn't this the same as the "Include Supertypes" #17 issue?
