fix: a deleted model is no longer the picked node, an orthophoto tile isn't swept as a grey stub, the ED brake arrays freed

Deleting a model in the editor left the renderer holding it as the picked node, the next pick used freed memory: the renderer forgets it now (Forget_Node). A texture filled straight from memory (internalsrc:) can't be read again, released by the garbage sweep it came back grey; it stays now, and the units bound with the old name are rebound. The arrays of the ED brake force sharing are vectors, they leaked once per update. The scene hierarchy and the editor menu items go through the translation. Python caches ignored.
