Fix for nodes not being advertised correctly.  * r6754 changed node advertisement to advertise keys as strings, so they were not picked up properly by the transition scripts.  * the advertised keys are casted into strings for lastadvertisedict, since some keys will be dicts, and dicts cannot be hashed to be used as keys in a dictionary.
