not the happiest with it, but it works alright. PageManager is
instantiated, you pass is Page{} objects, which have a (code)name, page
title, and url, and a show, hide, and shouldSkip function, each
returning a bool. The first two are self explanatory, the last tells you
if the page is disabled for some reason (like on setup some are disabled
if messages are). You can then call load(<(code)name>), or
prev/next(<name>).
