Plone.app.widgets

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

Breaking changes:


- Deprecate ``get_ajaxselect_options`` (no longer used).
``IWidgetsLayer`` and ``IWidgetsView`` are no longer used, remove them.
Deprecated ``IFileFactory`` import, use ``zope.filerepresentation`` instead.
Hard depend on ``plone.app.event``, it is meanwhile a dependenciy of Plone core.
Move ``IFieldPermissionChecker`` and ``Zope2FileUploadStorable`` to ``plone.app.z3cform`` in order to slowly fade out this package.
Use util ``first_weekday`` from ``plone.app.event`` and do not duplicate here; deprecated import placed.

Bug fixes:

- Modernize robot keywords that use "Get Element Attribute"
[ale-rt]

- Do not depend on `Products.ResourceRegistries` in `setup.py`.
In the code there is anyway no dependency.

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

Bug fixes:

- Minor administrative cleanups.

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

New features:

- Related items widget: show a recently used dropdown, but do not activate it.
plone.app.relationfield itself is activating the "recently used" feature.
The "recently used" dropdown is only available for Mockup 2.6.3+.

Bug fixes:

- Add Python 2 / 3 compatibility
[pbauer]

- Marked unstable robotframework test as noncritical.
And maybe fix it by using keyword ``Wait Until Page Does Not Contain Element``.
[maurits]

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

New features:

- Pass parameter of subwidgets to the query string widget to get them properly initialized.
Fixes a problem where the related items widget behaved differently from other areas and the date widget didn't respect the users localization.
