- minor UI changes for Gerber UI

- after an object move, the apertures plotted shapes are deleted from canvas and the mark all button is deselected
- fixed offset, rotate, scale, skew for follow_geometry. Fixed the move tool also.
- fixed offset, rotate, scale, skew for 'solid_geometry' inside the self.apertures.
