Title: API-only access, per issue #150

This implements an api-only mode, per issue #150. Actually it splits the issue into two settings which may be used independently or in concert:

requireSession: requires users to have a session (disables non-group pads)
editOnly: users may only edit existing pads - new pads can only be created via the api
