[Commands] Add #petitems Command. (#1823)

- Add #petitems command to show a person's pet items if they have access to the command.
- Adds a default false parameter to QueryLoot for NPCs that keeps messages and logic from being ran on pets for no reason.
- Cleaned up message a bit for loot and stuff.
- Remove check for loottable ID when using #npcstats for NPCs that get items from a script or otherwise.
