Title: add DijitRegistry#getParent

pls. add DijitRegistry#getParent for compatibility with dijit._KeyNavContainer

this is the code in dijit._KeyNavContainer

```
childSelector: function(/*DOMNode*/ node){
// Implement _KeyNavMixin.childSelector, to identify focusable child nodes.
// If we allowed a dojo/query dependency from this module this could more simply be a string "> *"
// instead of this function.

var node = registry.byNode(node);
return node && node.getParent() == this;
}
```

Grid is received from registry, but it doesn't provide getParent(). Any _WidgetBase descendant would provide getParent().
