Display LDName for LNodes

[jarradraumati]

Being able to see what LDName (combination of iedName and ldInst) that is associated with an LNode within the substation editor would help to see at glance what IEDs are mapped.

At present only the LNName is repeated upon hover-over.
It might be better if it was actually the LDName instead in the header (since the LNName is already present below the LNode symbol).

Here's a mockup:

At the moment, the only way to tell what iedName is associated with an LNode is to either:

1. View the xml code of the LNode
2. View the xml code of the container (e.g. bay, conductingEquipment, function)
