The index of the player that the current player is swapped with, if any.
There is only ever one swapped pair;
a member of a swapped pair dying means that neither member of the pair is swapped anymore.
This also means that there can be no background swapped pairs:
if the active player is not in a swapped pair, then nobody else is either.
