Plone.app.discussion

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

Bug fixes:

- Cleaned code from flake8 errors. [maurits]

- Removed ``comment-migration`` view. This did not work anymore on
Plone 5. If you still need to migrate from old-style comments, so
from Plone 4.0 or earlier, please upgrade to Plone 4.3 first.

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

Bug fixes:

- Reset the required setting of the author_email widget each time.
Otherwise, the email field might get set to required when an
anonymous user visits, and then remain required when an
authenticated user visits, making it impossible for an authenticated
user to fill in the form without validation error. Or when in the
control panel the field is set as not required anymore, that change
would have no effect until the instance was restarted. [maurits]

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

New features:

- Make tests work with lxml safe html cleaner

Bug fixes:

- Fixed possible cross site scripting (XSS) attack on moderate comments page. [maurits]

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

Products.PloneHotfix20160419. [maurits]

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

Fixes:

- Mark 'Edit' button for translation.

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

New:

- For the discussion controlpanel, change base URLs from portal URL to what getSite returns, but don't change the controlpanels context binding.
This allows for more flexibility when configuring it to be allowed on a sub site with a local registry.
