Adjusted CPQ drops to actually load from DB rathe than hard-coded.

Optimized Pet Item Ignore server handler performance.
Fixed some exploits and improved performance on PetLootHandler.

Fixed party player HPBar not accounting the player's HP stat gained on equips towards the effective MaxHP.
The duration of mists generated by mobs has been rescaled to 10x longer than what has been displayed until now (wz duration property is supposed to actually be in 100ms).
Optimized timer management for mob skill cooldown and elemental effectiveness.
Implemented an additional inventory check system, to be used in cases where it's expected to remove a set group for items (with quantity) to then add a new group of items.
Fixed Player Shop/Hired Merchant "vacancy" tooltip, now properly showing whether the store has a visitor room or is already full at that time.
Fixed Player Shops only using the standard stand type.

Fixed some minor PE exploits with players being allowed to create minirooms while dead or inside an event.
Adjusted item dropped from mobs to now allow visible quest items appear before not-visible ones, thus showing no "empty spaces" when the mob has multiple quest drops.

Removed unnecessary skill books from the drop data, since quests for them were recently implemented.
