Power supply symbols footprints dont work

Description

If you assign a footprint to a supply symbol (for example adding a solder pad to a +Batt symbol) does not produce a visible footprint inside the PCB Editor. I would expect to get the Footprint or to no being able to set one inside the properties window. However the first version would be better.

Its very handy to use for example the +Batt / -Batt power symbols as wire pad footprints.

Steps to reproduce

1. add a power symbol to schematic
2. open properties dialog of said symbol
3. add wire pad footprint
4. open PCB Editor and update PCB with changes from schematic
5. no footprint gets added, no error gets displayed
