Add PLC master IO table and PLC-slave group-index linking

Browse Source 
addPlcIO/setPlcIO/removePlcIO edit a PLC master's IO table (type,
address, function text, comment) directly through setElementData(),
the same as MasterPropertiesWidget's own PLC IO editor -- and, like it,
these are not undoable: MasterPropertiesWidget::associatedUndo()
deliberately returns nullptr for PLC masters, since their linking is
managed through the IO table rather than the link-tree widget it would
otherwise build an unlink-all command from.

linkElements() gains an optional groupIndex so a PLC slave can be
linked onto one specific IO row instead of leaving the row
unspecified. LinkElementCommand only reads the group index it is given
when the command's own element is the Slave -- when built from the
Master side (a=master, b=slave, the usual call shape) it looks in a
per-slave map this call never populates, and setGroupIndex() is
silently a no-op. Fixed by building the command from whichever of the
two elements is actually the Slave, matching what PlcLinkWidget does.
elementLinkGroupIndex() reads the result back.
