Modified donors.py, console.py, and testconnectandpopulate.py to change donor city, state, and zip fields into one field.   I can create an auction and all looks okay.  What's left is to modify the donor entry form.
Have completed mods to make the donor city, state, and zip fields be one field.  I may have found a defect where the item chooser is not updated after an item has been deleted.  I know how to fix it because that's what I had to do for buyers.  I need to test that some mroe first.
