Plone.app.z3cform

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

New features:


- Use label_css_class attribute from widget if available in checkbox_input & radio_input
[MrTango] (202)

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

New features:


- Add support for the "accept" attribute on file inputs.

If the widget's field - if there is one - has the "accept" attribute set (the
`NamedImage` field has `image/*` set by default) then this is rendered as an
`accept` attribute on the file input.

This would restrict the allowed file types before uploading while still being
checked on the server side.
