Load Halfword (ATTACK.OUT)

#   ROUTINE: LOAD HALFWORD (ATTACK.OUT)
#       Loads a halfword (2-byte) value from the specified memory address.
#       This appears to be the same as Load Halfword from BATTLE.BIN.  (Strange, because BATTLE.BIN routines should be available here...)
#       Parameters:
#           r4 = (ptr) Pointer to halfword value (potentially unaligned)
