* calcThreat() is also called in addThreat() when given proper parameters,
and division by 'size' is commutative
* threat redirection is also handled in addThreat() again
It may have been faster, but unfortunately made the aggressor threatened by his enemies instead of the opposite...
In case Player heals himself, this is of course pointless as he chooses target himself, hence it had no real effect at all.
Note: all spells with effect expect additional code for redirection reset.
Until code adding redirection work longer that expected.

Patch partly rewrited with move new data into HostileRefManager
and added redirection to threatAssist. Also bug fixed with
redirection threat to unit not in hostile list yet.
