[Quest API] Adds new methods to NPCs and Corpses (#1510)

Browse Source 
- Add $npc->HasItem(item_id) to Perl.
- Add $npc->CountItem(item_id) to Perl.
- Add $npc->GetItemIDBySlot(loot_slot) to Perl.
- Add $npc->GetFirstSlotByItemID(item_id) to Perl.
- Add $corpse->HasItem(item_id) to Perl.
- Add $corpse->CountItem(item_id) to Perl.
- Add $corpse->GetItemIDBySlot(loot_slot) to Perl.
- Add $corpse->GetFirstSlotByItemID(item_id) to Perl.
- Add npc:HasItem(item_id) to Lua.
- Add npc:CountItem(item_id) to Lua.
- Add npc:GetItemIDBySlot(loot_slot) to Lua.
- Add npc:GetFirstSlotByItemID(item_id) to Lua.
- Add corpse:HasItem(item_id) to Lua.
- Add corpse:CountItem(item_id) to Lua.
- Add corpse:GetItemIDBySlot(loot_slot) to Lua.
- Add corpse:GetFirstSlotByItemID(item_id) to Lua.

These methods will allow server operators to view the loot a current has in a slot, the first slot found by item ID, count the item by ID, and see if the NPC has the item.

With that functionality you could build a custom loot system and modify loot more dynamically.
