If an array property has elements defines in a Base config and an editor wants to configure the property to be empty in a Default config, nothing was being written.
The first problem was that only object properties with values are written to config files. In this case, we can use the !Property=ClearValue.
The second problem was handling this !Property case inside the config writing code. The code that detects array properties had to be adjusted to detect a !Property entry and check if the property is also empty in the config hierarchy.

### Virtualization
- [Core.ContentVirtualization] in the engine ini file now supports an array called 'DisabledAsset' which can be used to name asset types that should not virtualize their payloads.
-- By default (in BaseEngine.ini) we have disabled the StaticMesh asset as we know it will crash if a payload is missing and the SoundWave asset as it still is pending testing.
- This new way to disable virtualization is data driven. The older hard coded method has not been removed but will likely be reworked in a future submit.
- Now when an editor bulkdata is adding it's payload to the package trailer builder during package save it will poll the virtualization system with a call to the new method ::IsDisabledForObject by passing in it's owner.
-- If the owner is valid and was present in the 'DisabledAsset' array then the method will return true and the EPayloadFlags::DisableVirtualization flag will be applied.
### Package Trailer
- The pre-existing functionality of enum EPayloadFilter has been moved to a new enum EPayloadStorageType as will only filter payloads based on their storage type.
- EPayloadFilter has been modified to filter payloads based on functionality although at the moment the only thing it can filter for is to return payloads that can be virtualized, it is left for future expansion.
- EPayloadFlags has been reduced to a uint16 with the remaining 2bytes being turned into a new member EPayloadFilterReason.
- This new member allows us to record the exact reason why a payload is excluded from virtualization. If it is zero then the payload can virtualize, otherwise it will contain one or more reasons as to why it is being excluded. For this reason the enum is a bitfield.
- Added overloads of ::GetPayloads and ::GetNumPayloads that take EPayloadFilter rather than a EPayloadStorageType
- Added wrappers around all AccessMode types for FLookupTableEntry.
- FPackageTrailerBuilder has been extended to take a EPayloadFilterReason so that the caller can already provide a reason why the payload cannot be virtualized.
-- As a future peace of work this will probably be changed and we will ask the caller to pass in the owner UObject pointer instead and then we will process the filtering when building the package trailer to a) keep all of the filtering code in one place b) keep the filtering consistent
### PackageSubmissionChecks
- The virtualization process in will now request the payloads that can be virtualized from the package trailer, which respects the new payload flag, rather than requesting all locally stored payloads.
### UObjects
- There is no need for the SoundWave or MeshDescription classes to opt out of virtualization on construction. This will be done when the package is saved and is now data driven rather than being hardcoded.
### DumpPackagePayloadInfo
- The command has been updated to also display the filter reasons applied to each payload

Give RingBuffer its own iterator class since RemoveCurrentSwap does not fit the usual usage of a ringbuffer, which is supposed to maintain order.

This fixes replaced actors being considered as the package asset when replacement actor is the better choice. (AActor::PreSaveRoot was being called on wrong actor)

* Added new ELifetimeCondition COND_NetGroup, that is only supported on replicated subobjects.
* Any subobject using COND_NetGroup must be part of a netcondition group via the NetConditionGroupManager world subsystem for it to get replicated.
* PlayerControllers can be members of a group via IncludeInNetConditionGroup
* When a netgroup subobject replicates to a connection we will only replicate it if the playercontroller of the connection is a member of atleast one group of that subobject.
* NetGroupOwner and NetGroupReplay are special groups that automatically replicate to the owner's connection or the replay net driver.
* This feature is only available to Actors or Actorcomponents with bReplicateUsingRegisteredSubObjectList = true

- This is most likely to occur when trying to load a package trailer from a corrupted 0 byte file.
- Currently we load the footer then check that the package tag exists to confirm that the package file is malformed
- We need to check that there is actually room for us to seek backwards to the potential start point of the footer otherwise FArchive code will assert on a negative seek position.
