Loot Table improvements

Eliminated most of the 'junk piles' that accumulate and cause problems.
No more invisible piles of hundreds of useless potions, armors, and
weapons. Converted most of these garbage drops into shillings instead.

Avars no longer drop nerudite armor or swords (instead shillings)
Chieftains drop far more arrows now, and less bows
Shamans drop a lot more and better reagents (they were terrible value
before)
Fairies and skeletons of all types had their 'junk' converted to
shilling drops
Brax drops improved to compete a little better with Thrashers
Cave orc drops had their 'junk' removed and replaced with money

Players should have a much nicer loot experience overall.
