[Quest API] Add EVENT_EQUIP_ITEM_CLIENT and EVENT_UNEQUIP_ITEM_CLIENT to Perl/Lua. (#2015)
- These events allow more customization beyond forcing operators to use a script file for each and every item they want to have some sort of functionality for these events.
- Perl event exports $item_id, $item_quantity, and $slot_id.
- Lua event exports item_id, item_quantity, slot_id, and item.
