Fix netlist generation bug cause when component unit is set to zero. 

Fix if statement logic to ensure the unit number is never set to zero.

Add logic to the legacy schematic plugin to automatically convert any
schematic files that have components with a unit setting of zero.  Set
the schematic modified flag so that the user will be notified of a
changed schematic.

Add a user warning when the schematic parser fixes the bug and sets
the file modified flag.
