* Core/Creature: Add new db field InteractionPauseTimer
Add new db field InteractionPauseTimer to allow to define different interaction pause timers for each creature (the previous system was a global setting in worldserver.conf Creature.MovingStopTimeForPlayer)
* Set all columns in creature_template_movement as optional (can be NULL, default NULL). Fill only the columns that should override the default C++ value
* Use the InteractionPauseTimer value throughout the code instead of Creature.MovingStopTimeForPlayer
* Handle InteractionPauseTimer set to 0 as "don't stop at all"
* Implement InteractionPauseTimer in creature_movement_override
creature_movement_override allows NULL values, in which case the values from creature_template_movement will be used for those columns that are NULL, falling back to default C++ values if creature_template_movement has NULL values too (or no rows for the creature)
* Read default InteractionPauseTimer from worldserver.conf
* Rename 2021_99_99_99_world.sql to 2021_01_22_00_world.sql
(cherry picked from commit a22bc236eb)
This is neccessary so that GameObject::BuildValuesUpdate from BuildValuesUpdateBlockForPlayer picks up correct inventory state and sets GO_DYNFLAG_LO_ACTIVATE
(cherry picked from commit 449bd9058b)
* 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)
