Sketcher: Ellipse enhancement: All internal geometry is shown on creation

Browse Source 
Elements that have internal geometry are created with the internal geometry on creation.

It has been under discussion for a long time. Ulrich was in favour (asked for it several times).
DeepSOIC implemented the focus because he hated the poor dragging of the ellipse when empty.
