Hide Menu Items - unless logged in as a manager

The way to split a couchapp into a public website and an administrative backend is to put each of the following in its own database and design doc:

- the public website,
- the administrative backend
- each user's data

Hoodie does this well in the following manner:

- the public website - in a per-user copy of the app (each copy is one db and design doc)
- the administrative backend - in Hoodie's Pocket
- each user's data - in each user's database

So to implement the administrative backend, we should try converting the app to use Hoodie.
