Plone.app.z3cform

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

- Include plone.z3cform's overrides.zcml from our own overrides.zcml.
[optilude]

- Updated to collective.z3cform.datetimewidget>=0.1a2 to fix a ZCML conflict
with z3c.form.
[davisagli]

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

- Made the KSS form support conditional on both kss.core and Archetypes being
installed.
[hannosch]

- Use the date/time widgets from collective.z3cform.datetimewidget as the default
widget for Date and Datetime fields.
[davisagli]

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

- Made the KSS validator use traversal instead of getMultiAdapter() to find
the form. This makes it work on add forms.

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

- Added a display template for the WYSIWYG widget.
[optilude]

- Make the ?fieldset.current query string variable work. Set it to the id
of a fieldset other than default to pre-select a different fieldset, e.g.
.../formview?fieldset.current=3
[optilude]

- Hide the 'default' fieldset if there's nothing to show there.
[optilude]

- Provide 'portal' variable in wysiwyg template, as its used by some editors.
[davisagli]

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

- Make the WYSIWYG widget work also for non-Acquisition wrapped
content.

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

- Removed maximum version dependency on zope.component. This should be left
to indexes, known good sets or explicit version requirements in buildouts.
If you work with zope.component >= 3.5 you will also need five.lsm >= 0.4.
[hannosch]

- Make use of new plone.z3cform support for looking up the layout template by
adapter. This means that forms now no longer need to depend on
plone.app.z3cform unless they want to use Plone-specific widgets.
