Change GODNEWS reports not to affect headlines and relations

Option GODNEWS controls news reports give's N_GIFT, N_TAKE, and edit's
and setsector's N_AIDS, N_HURTS.

They affect news headlines because of their non-zero r_good_will.
N_TAKE and N_HURTS can downgrade relations because of their negative
r_good_will.  All tolerable, except N_TAKE has actor and victim
reverted: the deity running the give command is the victim, and the
sector owner is the actor.  Because of that, give with a negative
amount downgrades the deity's relations towards the sector owner.
Inappropriate.

Has always been that way.  Chainsaw disabled these news at
compile-time; to enable you had to define GODNEWS (not documented
anywhere).  Empire 4.2.0 made GODNEWS a proper option, enabled by
default.

Fix by setting their r_good_will to zero.
