While trying to process all slices and levels in Automated Testing, a few bugs came up that needed to be addressed:
- [LYN-3832] TransformComponent had a field removed without updating the version number and converter, which caused a lot of excessive warnings
- SliceComponent would crash in debug builds on instantiation failures due to a null dereference that was guarded against in most but not all places
- SliceConverter now detects when nested slices exist and gracefully warns about it.
- InstanceUpdateExecutor / TemplateInstanceMapper will now immediately remove instances that are unregistered, so that any in the queue don't get processed on a subsequent tick. This was causing crashes when the instance was destroyed before the processing occurred. It also has a side benefit of preventing the same instance from executing multiple times.
- Minor logic bugfix to the pack close warning, the boolean check was flipped.
Also added an early-out on SetTemplateId, since this was causing some unnecessary instance queue entries.
- Uses ToolsApplication instead of ComponentApplication so that built-in Editor components are recognized and read in correctly
- Starts up all the DynamicModules immediately so that the System Components are activated, which registers asset handlers and allows asset references to serialize in correctly
- Adds a -specialization command-line flag to specify which project specialization to use (editor, game, etc)
- Removes the filter to ignore unknown classes since they should all now be "known"
- Adds a few gem autoload flags and a null thumbnail service so that Qt and Python systems can be skipped, as they aren't needed for the data conversions and would bring additional overhead and complications
