Fix combat logging

In the initialize section of the fsm r_player_unconscious and
r_player_timeout return their default values (false and 0). Also, the
Vanilla server-side combat check doesn't appear to work, or it doesn't
work with the antihack disabled (I haven't tested with it enabled).

New variable inCombat is set more quickly than the combatTimeout
variable
