/ DESCRIPTION:
/ Inter-terminal battle is a very fragile and slightly klugy thing.
/ At any time, one player is master and the other is slave.
/ We pick who is master first by speed and level. After that,
/ the slave waits for the master to relinquish its turn, and
/ the slave becomes master, and so on.
/
/ The items in the player structure which control the handshake are:
/ p_tampered:
/ master increments this to relinquish control
/ p_istat:
/ master sets this to specify particular action
/ p_1scratch:
/ set to total damage inflicted so far; changes to indicate action
