Minor LDCad annoyance

[Orion Pobursky]

I have a minor LDCad annoyance that would be cool if it were addressed in 1.6d or later. When you click the "Add submodel" button (or the menu entry) and then subsequently change your mind and click "Cancel" on the ensuring dialog, a submodel is still created with the default name. This normally wouldn't be a huge issue (and, to be honest, it isn't now) but the "Add Submodel" button is right next to and looks very similar to the "Open main submodel" button. Sometime I accidentally click the wrong button and it would be nice if the cancel button actually cancelled the creation of a new submodel.
