This rev. improves the QuickCreate widget for grouped Kanban views.
It allows specifying in the Kanban arch a form view xmlid, e.g.:
<kanban quick_create_view="some_form_view_xmlid">
...
</kanban>
When this attribute is set, the referenced form view is loaded and
rendered inside the QuickCreate widget. A real FormView widget is
instantiated, meaning that all form view mechanisms are available
in the QuickCreate (modifiers, default_get, onchanges, widgets...).
