Plone.app.controlpanel

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

Bug fixes:


- Minor packaging updates. [various] (1)

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

Breaking changes:

- Now this packages should not be needed in Plone 5.2 core anymore.
It will be removed there as dependency.
Addon code then needs to depend on it directly if backward compatibility is needed.
This works not in Plone 5.1 and lower.
