- fixed a bug in Excellon Editor that crashed the app when editing the first tool added automatically into a new black Excellon file

- made sure that if the big mouse cursor is selected, the utility geometry in Excellon Editor has a thicker line width (2 pixels now) so it is visible over the geometry of the mouse cursor
