Document the behavior of propagation of changes for Site Templates with Content Pages.
State that propagation affects to widget pages. As an additional clarification, we might want to add that other kind of pages (such as "full page applications") and so forth are also propagated. This should be done in the Site Template Page Behavior section
State that content and display pages behave like app data: this can be done in the note where we talk about this, at the bottom of the page
As a side note, we can also clarify that, in a site, pages coming from the template appear before pages added to the site in the site page hierarchy.
