New syntax, "party swap [player] <row>,<col>", which
forces a player to that position. Acts as a party place
if the position is free, and party swap if the position
is occupied. The old "party swap [plr1] [plr2]" acts as
before, as does party place.

Also, I removed one occasion where party leader loses
party position, please tell me if you find a way to
get party leader to ?.? and I'll see if I can fix it.

Effective after boot.
