Move edge highlighting

When selecting an edge that is perpendicular to the view using the moveEdge command it does not highlight. Previously it did.

For example, selecting a vertical edge on a box when in top view, you can select the edge but there is no UI highlighting that it is indeed selected.

Another issue, having moved a vertical edge on a newly created box, the display of the box is shown strangely with a double and non parallel line.

Exploding the box didn’t get rid of this (ie the single face was still displaying incorrectly), but having deleted the surface and used the cap command, the newly created polysurface is displayed correctly now.
