Determine which policy templates to use based on database properties

[jaguillette]

In the current state of the app, the active policies are hard-coded into the views in the app, so that adding, removing, or changing which policy templates are presented to users requires a change to the application code.

It would be preferable to be able to make these changes with database edits. This would require adding a field to the database to indicate whether a policy template is active or not, and would require additional logic and templating in the application.
