Stat Increment/Decrement

Parameters : r4 = Stat Change (0x7f = holds value - 0x80 if it's a bonus)
             r5 = Unit Stat data pointer (details in return location)
             r6 = Stat maximum cap
             r7 = Stat minimum cap
             
Returns : r2 = 0x00 if no stat change
          r2 = 0x01 if stat changes
