This revamps the old database apps/models listing, making it

mobile-friendly and a bit sleeker and removing the dependence on

Django's own styling.
The new version provides a single column of apps and models, with the

Add link appearing as an icon to the left of the model instead of an Add

and a redundant Change off to the right.
Above the listing is a warning telling people to be careful when making

changes. If the user doesn't have permission to even view the

information on this page, they'll simply receive an error alert stating

so.

Tested that the links worked.
Tested the appearance on desktop and mobile at various widths.
Simulated access issues to models and the app list, and verified results.
