- Switch resources to routes.
- No longer nest "settings" routes so the router reflects
the way the templates are rendered.
- Remove renderTemplate override from settings routes.
- Remove unneeded routes, controllers, and views.
- Adjust users page so that infinite scroll loading of users works
and markup remains the same for Zelda styling.
