setFFState: Save team wound count & warning state before an attack

The purpose of this is so that we can increment team_wounds by 1 for
each real attack instead of just counting each bullet/pellet/shrapnel
as a wound. The ff_warning flag is so that we don't overflow the
clients from repeated FF warnings. Hopefully the overhead on this 
will be low enough to not affect things.
