Maintenance release...
Maintenance release * `NodeList-fx` added overloads to all methods to distinguish returned values of different types (`Animation | this`). * Added missing signatures to `NodeList` constructor * Improved `dijit.form._FormWidgetMixin` * Added module declarations `dijit/form/_FormWidgetMixin`, `dijit/form/_FormValueMixin`, `dijit/_HasDropDown`
