Plone.app.z3cform

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

Bug fixes:

- Remove ZopeTestCase.
[ivanteoh, maurits]

- In select widget, accept items as property or method.
This avoids breaking on some z3c.form versions.
See https://github.com/zopefoundation/z3c.form/issues/44
[maurits]

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

Bug fixes:

- Enable unload protection by using pattern class ``pat-formunloadalert`` instead ``enableUnloadProtection``.
[thet]

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

New features:

- Related items data converter supports explicit value_type specified in
field when using collections of UUID values. This is backward-compatible
with previous conversion to field values, supports str/unicode value(s),
whichever is specified by field.
[seanupton]

- Support functions as values in the ``pattern_options`` dictionary, which gets then serialized to JSON.
Before that, walk recursively through ``pattern_options`` and call all functions with the widgets context.
This allows for context-specific, runtime evaluated pattern option values.
[thet]

- Don't overwrite widget default css classes when rendering pattern widgets.
This allows setting a css class via the ``klass`` keyword in plone.autoform widget directives.
[thet]

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

Incompatibilities:

- Deprecated "plone.app.z3cform.object" and moved to
"plone.app.z3cform.objectsubform" in order to avoid built in names
as module names, which may result in difficult to debug errors.
[jensens]

- Made existing soft deprecation (by comment) of plone.app.z3cform.layout
explicit by deprecating using zope.deferredimport.
[jensens]

- removed plone.app.z3cform.queryselect since this was deprecated already
and removal planned (!) already for Plone 4.1
[jensens]

New:

- make widget available to wysiwyg_support template
[gotcha]

Fixes:

- Reduce dependency on plone.app.widgets in tests.
[thet]

- Enhance test in order to show problem in RelatedItemsWidget with
navigation-roots
[jensens]

- Cleanup: pep8, uth8-headers, zca-decorators, ...
[jensens]

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

New:

- Add metal slot for inserting stuff below fields
[fredvd]

Fixes:

- Fix ajax selection for add forms
[tomgross]

- Use doctest instead of zope.testing.doctest
[pbauer]

- Fix related items widget tests to include root path support.
Fix options merging for TinyMCE widget.
[alecm]

- Fixed test for plone.app.widgets.
[Gagaro]

- Used assertDictEqual instead of assertEqual for RelatedItemsWidgetTests.test_widget
[Gagaro]

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

Fixes:

- Fixed tests for newer CMFPlone. [Gagaro, ebrehault, vangheem]
