Subject: * Moved most hard-coded non-standard unrandart behaviour to
 art-func.h,   specifically code for equipping, unequpping, an equipped
 unrandart doing   something every time world_reacts() is called (special
 wield effects),   melee hit effects, and evoking.  Left hardcoded outside of
 art-func.h:

  * Sword of Cerebov temproarily downgrading the defender's fire
    resistance.

  * Staff of Olgreb boosting poison spells, as if it were a staff
    of poison.

  * Vampire's Tooth always getting maximal vampiric drain.

  * Mace of Variablity's initial pluses being chosen at creation time.

* Since what used to be special wield effects is now handled very
  differently, noisy weapons and the lantern of shadows effects
  are handled with player attributes rather than SPWLD_NOISES and
  SPWLD_SHADOW.

* Unrandarts can now have an elemental colour for their colour
  (currently only used for the Mace of Variability).

* Unrandarts' value modification, being special, and being
  evil are now handled in art-data.txt rather than being hardcoded.
