* Add pet when learning it for the first time (summon spell not known).
* Removed code that adds battle pet if its summon spell is known (Learn cageable pet -> Cage pet -> Log out -> Log in -> Pet is added).
* When uncaging check that the species has a summon spell before trying to learn it.
* Rename WorldPackets::BattlePet::BattlePet::CollarID to WorldPackets::BattlePet::BattlePet::DisplayID
* Use the DisplayID field to store the model of the battle pet. If the species has BattlePetSpeciesFlags::RandomDisplay, nothing is stored. Otherwise a random model is chosen from those available
* Stored DisplayID in ITEM_MODIFIER_BATTLE_PET_DISPLAY_ID when caging the battle pet (previously the CreatureID was being stored)
* Modified SendPlaySpellVisual function to allow sending Target and TargetPosition at the same time
* Added SpellVisual when uncaging
* Add CREATURE_FLAG_EXTRA_NO_SELL_VENDOR and use it for a single no-sell vendor in game (there are more of them in later expansions)
