This makes it possible to "reload" the Ptrs in active cells when changes happen to the ESM record that they are based on. In practice, the old Ptrs are deleted, their RefNums and MpNums are blanked out, and new Ptrs are created that use the same RefNum and MpNum as before.
The above has required me to also add a method called setRefNum() to CellRef to allow setting a RefNum on the fly.
There may be a more elegant implementation available for updatePtrsWithRefIds(), but it requires additional research.
Previously, attempts to reuse the same reference for multiple creature disguises led to movement animation issues, as well as a dynamic_cast error in Creature::getInventoryStore() that made a DedicatedPlayer vanish completely when they first lost their creature disguise, then disguised themselves as a creature that could not hold weapons and then disguised themselves as a creature that could hold weapons.
The usage of const_cast has been replaced with usage of MWWorld::getModifiableStore() and ESMStore::overrideRecord()
Methods whose names started with "update" now start with "override", for consistency with ESMStore's overrideRecord()
New methods have been added for "overriding" enchantment, potion and spell records, which actually leads to them being created with their already set refIds if they haven't been created yet, as per the description of ESMStore::overrideRecord(): "Insert a record with set ID, and allow it to override a pre-existing static record."
Usage of RecordHelper methods has been updated in DedicatedPlayer.
Actors who are on the ground have their inertial force ignored, so they are now made to not be regarded as being on the ground in World::setInertialForce()
I originally added rotation animation sync as part of commit 068a45be87. Unfortunately, it meant the PlayerPosition packets were now twice as large as they had been before, which was less than ideal for such a frequently sent packet, which is why Koncord switched to a more optimized approach in commits 5f30dfd5db and d67db1a9bd.
Recently, there have since been some rotation animation problems in OpenMW, which have broken the way Koncord's approach looks. My original approach still looks somewhat okay, so I'm switching back to it until we can figure out how to reuse it under the current circumstances.
