Provide the ConfigPagesView in the ConfigPage constructor.
Review Request #5597 — Created March 7, 2014 and submitted
It's useful for ConfigPage subclasses or their forms to have access to
central state computed for a ConfigPagesView. Now, ConfigPages are
provided with the view when being constructed. ConfigPages already pass
themselves to ConfigPageForms.
Created a ConfigPagesView that fetched some objects from the database.
The ConfigPages then accessed the objects without having to re-fetch.
