Make being hit by an artifact which does fire, cold, or
lightning (or magic missiles, since the code is there) affect
inventory even when the target resists the damage him-/her-/itself.
This removes the need for the redundant fire vs slime handling that
I put in yesterday. Unfortunately it also means that Valkyries who
throw Mjollnir will inevitably end up destroying all their mettalic
wands and rings, so I reduced the chance of it hitting upon its
return.
Being hit by Fire Brand now stops the sliming process if you're
being turned into green slime. And throwing an artifact up will give
artifact hit effects when it falls back down, making it possible to
hit yourself with Fire Brand (among other things). Hitting yourself
with Vorpal Blade or the Tsurugi of Muramasa will never behead or
bisect you; hitting yourself with Stormbringer will drain levels.
(I hope the latter doesn't make it too easy for players to manipulate
their experience level.)
This doesn't add artifact_hit() handling to mthrowu. If monsters
ever start throwing artifacts that will need to be added.
Addresses the follwing missing updates:
- Quest Artifact identification by Quest Leader.
- Rust damage from a rust trap.
- Remove curse as a result of prayer (both fixing TROUBLE_CURSED_* and
the blessed-remove-curse boon.)
- Charging via PYEC
