Collective.mailchimp

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

New Features:

- Make plone.app.imaging a test dependency only in setup.py. This fixes an
issue with Plone 5.1 and plone.restapi. plone.app.imaging is a hard
dependency on Plone 5.0 (CMFPlone) and optional on Plone 5.1.

- Updated to version 3.0 of the mailchimp api. The data that we get
from mailchimp with this api version is changed. When you have
interest groups in your lists, and you do not see them anymore on
the subscribe form, you should visit the control panel again. This
will update the data automatically.
[jladage, didrix, maurits]

- Remove bare excepts.
[timo]

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

- Try to avoid some needless registry updates.
[maurits]

- Disable inline validation in the mailchimp control panel. It may
change the cache based on a new api key that the user has not yet
saved.
[maurits]

- Remove mailchimp object before updating cache. Otherwise a change
in the api key is not picked up until after a restart.
