Translate between kernel and model/javascript node references.

The translation is performed for each value (property value, method or
event parameter, or return value) that crosses between the kernel and
the model/javascript driver. This allows components to make persistent,
direct node references. Nodes may be assigned to properties and passed
through methods and events.

Replicate node references.

Regular properties replicate as `{ propertyName: value, ... }`, or the
more general `{ propertyName: { value: value }, ... }`. Extend the
general form to encode properties containing node references as `{
propertyName: { node: nodeID }, ... }`.

The `node` field indicates that the property is a node reference instead
of a simple value. Using a distinict field ensures that the reference
won't be confused with any other value that could otherwise resemble a
node ID.

Support property node references in `kernel.createChild`.

Support properties containing node references in `kernel.createChild`,
in addition to `kernel.setNode`. Node references are only valid during
replication, but properties of nodes created during replication are
assigned in `kernel.createChild` and not `kernel.setNode`.

Node references are property descriptors in the form:

    { properties: { p: { node: id } } }

This is in contrast with regular property values, which have descriptors
in the form:

    { properties: { p: { value: v } } }
Accept node references in `node.children.create` component descriptors.

Clarify names that reference the proto-prototype node `node.vwf`.

Rename the `kernel/utility` items `nodeTypeURI` and `nodeTypeDescriptor`
to `protoNodeURI` and `protoNodeDescriptor`, respectively, to better
reflect that they refer to the proto-prototype node.

Rename the `model/javascript` internal variable `nodeNode` to
`protoNodeNode` so that it parallels the `protoNodeURI` name it derives
from and to hopefully clarify that it is the `model/javascript`
`...Node` data for the `protoNode...` node.
