Example Syntax Errors in _TemplatedMixin and dojox/mobile/internationalization

* Add the missing `registry` dependency to the dojox/mobile/internationalization example
* Fix breaking _TemplatedMixin containerNode example
    * remove old `dijit.` syntax on `_WidgetBase` and `_TemplatedMixin`
    * remove explicit call to `parser.parse()` as it is running before `MyButton` is defined. Instead, change `parseOnLoad: true` for this example.
