Get Base Job (Formation Screen)

#   ROUTINE: GET BASE JOB (FORMATION SCREEN)
#   Gets the base job of a unit based on its formation screen index.  For generics, returns the actual job ID of the base job (Squire, or Monster job)
#       Parameters:
#           r4 = (formationScreenUnitIndex) Index (order) of the unit in the formation screen.  Not the same as the unit index, as it will differ for guests.
