Resolve the issue discussed [on the mailing list](https://groups.google.com/forum/#!topic/symfony-cmf-devs/TveydplYnWY), with menu options not being able to be set on the Page document.

Does this by providing additional properties and accessors on the Page document to match the options in MenuNodeBase, and returning them in getOptions().
