With "Show the properties of a selected conductor in the Selection
properties panel" switched on, editing a wire there could change things
the user never touched:
- Enter in a field (Function, Section...) is not used by the line edit,
so it reaches the checkable "Multifilaire" group box around it, which
takes it as a click. The wire was switched to single-line, gaining
ground, neutral and phase symbols. The modal dialog never shows this
because its OK button takes Enter first.
- Every edit wrote back the whole set of properties as the widget holds
them, so a value the widget cannot show exactly was rewritten: a dash
size of 1 became 2.
The panel now swallows Enter at its checkable group boxes, and writes
only the fields that differ from what it showed, through the new
ConductorProperties::applyChanges(). "Apply to all conductors of this
potential" uses the same rule, so the rest of the potential keeps its
own values too.
tst_conductorapplychanges checks each field on its own: change that one
field, and a wire whose every field differs takes it and keeps the rest.
