⦁ TOWN: Shop discount based on the margin of success of the haggle check.

⦁ TOWN: Added "use" and "equip" to town menu.

⦁ Bugfix: Energy of monsters encounted in "tired" state now correct.
⦁ Bugfix: Harvesting a thing now correctly gets base item from database (so the thing has a weight, so can be taken. Not sure when that was broken).
