Sound overhaul: sound where spell hits

Directed spells now do noise where they hit a monster/player, rather
than where they're cast (enchantment spells have 0 noise when they hit);
casting these spells generates a noise of loudness 1 where the spell
caster is.  The noise level is hard-coded in beam.cc's zap_data array
(and setup by zapping()), and is constant regardless of the amount of
damage done or the beam's power.  Beam-ish spells generates a seperate
sound event for each target hit.  Spells which miss generate no noise.
