Prefab Tool - Prefab Support for Unreal Engine

@Yun-Kun, to fixed the blueprint rename issue with 1.0.3 version:

  1. Rename Blueprint Asset back to original name when Prefab was created
  2. Drag the prefab to level, verify if it’s in right state, then click “Apply” to update prefab content
  3. Then you can rename Blueprint Asset to new name, and fix up redirectors

Let me know if there’s still any issues
