Add a new custom module property 'original_id' indicating
the equipment_id the modules originally belongs to.
This property is only given, when distinct from the equipment_id
of the SEC node.
It happens when multiple config files are given, for all modules
but the ones given in the first file, and for routed modules,
when multiple nodes are routed or own modules are given.
+ fix an issue in router: additional modules were ignore in case
of a single node.
+ small cosmetic changes in config.py reducing IDE complains
