[9947] More skinning fixes.

* Restore work with money loot.
* Old code sometime generate empty loot windows for normal loot and sometime skip its.
  Code changed to be more consistent. Added new option Corpse.EmptyLootShow that control
  show empty normal loot window in some cases enabled by default:
   - if creature expected to be lootable but loot generated empty by some reasons.
   - if creature can be skinnable
  If option disabled thne code attempt avoid empty normal loot windows for empty cases.
* Possible fixed case instant despawn non-skinable creature after normal loot complete.
