Changed management to just show all controls

This is the first of a series of CLs to update management screens to
latest mocks. Now ControlModel is an interface to interact with the
Adapters. Different implementers can be used to surface different views
of all the controls.

Zones are now sorted according to the order they appear on load. Zones
with no name (or blank name) are given a generic "Other" and put at the
end.
