Page Object Access

It isa often handy to be able to access the page object for other pages (in my case, so I can build a nav bar). You can't do this easily in standard Albatross, because the Page Objects are stored in the PageObjectMixin in a class-local variable. So I had to wrap page_resgister() in my Application class and duplicate the __page_objects map.

Or we could expose the Page Objects a bit more directly:
