patch

Add CatalogIndexPage and CatalogEntityPage, two new extensions that replace the existing Router component.

Add EntityLayout to replace EntityPageLayout, using children instead of an element property, and allowing for collection of all RouteRef mount points used within tabs.

Add EntitySwitch to be used to select components based on entity data, along with accompanying isKind, isNamespace, and isComponentType filters.
