Feat - automatically remove objects spawned with zero-width names

[PowerUser64]

After starting the process of adding an object by typing in its name, if you delete the text you have typed, you are left with a blank red object box that has no text in it. Instead of leaving the object as a blank red box, I think it would probably be best to delete it. This would allow cancelling the action of adding an object by simply deleting the text you typed and clicking out of it, which (at least to me) makes the most sense from a UX standpoint.
