Corrected an error in which the "global substrate node" flag does 

not get transferred to a new node during a node merge;  consequently,
the identity of the default substrate node gets lost, and node
capacitance to substrate ends up being placed on node "0"---
Probably okay for simulation, but not the expected result.
