For non-random page applications __page__ is already set when you
enter load_page_module().  For the time being I think that the right
place to set __page__ would be back in RandomPageModuleMixin.

It is probably a good idea to use ctx.locals.__page__. in
RandomPageModuleMixin.load_page() rather than ctx.locals.page_name.
