Plone.app.z3cform

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

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]

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

Fixes:

- Don't allow adding new terms in the AjaxAutocompleteWidget
when it's used with a Choice field.

compatibility.
