User defined gizmos will haave higher preference than editor gizmos by
default. Also fixed some inconsistencies in the gizmos menu when using
custom gizmos.
-Missing Icons
-Missing freezing option (for baking light and faster load)
-Missing a way to export from Godot (GLTF2?)
-Probably buggy (may freeze editor, can be worked around easily, but let me know if this happens so it's easier to catch bugs)
Happy testing!
