when Interface() data is loaded directly from gmoc, Interface._resource is not set

[chaos@bbn.com]

When a resource with interfaces is loaded from gmoc using e.g.:

obj = client.load(gmoc.Resource(resourceinfo['urn']))

each interface of that resource correctly has Interface._resource set to the value of the resource.

However, when an interface is loaded directly from gmoc using e.g.:

obj = client.load(gmoc.Interface(interfaceinfo['urn']))

that object has Interface._resource = None.

Dan fixed this last week while we were debugging.
