generated element would be lacking the name attribute.

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

* Use full widget name in ++widget++ path, don't try and remove form prefix
(which will not behave correctly if widget is part of a subform).
[lentinj]

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

* Add upgrade step to register formwidget-autocomplete.js, bumping profile
version to 1
[lentinj]

* Split input:radio adding function so the code can be reused when adding
in plone.formwidget.contenttree
[lentinj]

* Move the javascript callback to real code, so instances of the widget
can be added to the page by cloning existing widgets
[lentinj]

* Allow overriding of the autocomplete URL
[lentinj]

* Fix htmlDecode to return an element, not the nodeValue of an element which
is null.

* No longer include the `demo.zcml` by default, but rather allow users to
include it if needed.

* Update distribution metadata.
[hannosch]

* Remove direct `zope.app` dependencies.
[hannosch]

* Use the correct ViewPageTemplateFile from Five required in a Zope 2 context.
[hannosch]

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

* Explicitly include CMFCore's zcml in demo.zcml, for compatibility
with Zope 2.13.

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

* Force the inserted HTML radio buttons to be interpreted as HTML
instead of text.

* Fall back to the site to perform content-related operations if the
context is not wrapped into an aquisition chain.
[dukebody]

* Compute the view name as the request URL left-stripped the content
absolute URL.
[dukebody]

* Use the same display template for single- and multi-selection:
The single selection display template was non functional before.
The value of a single selection field is wrapped in a list anyways
so the multiselection template renders the single selection field
just fine.

* Update widget in the autocomplete-search browser view:
The self.context.update() call rebinds to source which previously
was only bound during traversal. This avoids problems with
sources that only work after security is applied.
