Plone.app.portlets

------------------

- Don't create persistent objects during module import -- it breaks test cases
that are sandboxed into different ZODBs and import this module (leads to
ConnectionStateErrors).
[davisagli]

- Rework page templates for group prefs pages so that they match the rest of our
prefs pages. Add the group dashboard link to other group prefs pages. Closes
