#   ROUTINE: GENERATE PARTY UNIT IN EMPTY SLOT
#       Parameters:
#           r4 = unitType (Parameter for Out of Battle Unit Generation)
#               0 = Male
#               1 = Female
#               2 = Ramza (Initial Ch.1)
#               3 = Monster
#       Returns:
#           r2 =    (Unit index) of generated unit, if an empty slot was found to generate the unit;
#                   -1, if no empty slots were available and no unit was created
