Ever created a new Prefab, dropped it in a scene, pushed the change to the scene forgetting to also add the new prefab & meta?

This editor script is designed to catch the cases where files/assets referenced by your currently staged files haven't yet been tracked by Git. If no files are staged it also checks the previous commit didn't miss some files. The script runs whenever the editor newly gains focus - might be heavy on large projects - relatively untested.

Please take and customise if useful.
