Fix: remove forge quality from artifacts obtained via crowning.

Noticed this while playing as a caveman. I had a spear of superior
quality, had it wielded when I prayed to my deity while standing on a
co-aligned altar (lawful). Deity crowned me, transformed my spear into
Giantslayer, and I noticed the forge quality was still present.
Artifacts aren't supposed to have any level of forge quality other than
'normal' (meaning none).
