Oops, re-enable transform graph building in sceneloader
Allow non-existing directories in LoadOrder.json
Proper transform graph serialization

May need to revise this. Id's not necessarily unique between runs, will
cause issues when importing Transforms serialized during a previous run.
Perhaps generate a UUID for every component on construction?
Wrap default main in a version block

Default main can now be disabled using version KratosCustomMain
Allow access to owning entity during Component construction
