Plone-app-z3cform

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

- Corrected formatting for errors on the FieldWidgets object (i.e. from
invariants). This closes http://code.google.com/p/dexterity/issues/detail?id=238
[davisagli]

- Added the ``i18n:domain`` attribute in the first ``div`` of ``widget.pt`` in order to make the
"required" tooltip translatable. Fixes http://dev.plone.org/plone/ticket/12209

PicklingError on Plone 4.1.

- Change inline validation to match archetypes behavior - add a warning class and
omit the error message.
