Snap redlining + Corrects Cesium duplicated shapes

Description

• Snap redlining to terrain (solves #204 (closed))

• Corrects an event order issue that add multiple geometries in Cesium for one redlining shape. When drawing a shape while the 3D Cesium panel is open, the order in which the event are received by OlCesium was incorrect. This was creating multiple instance of the shape in the 3D view.

Job done

• All the vectors in the 3D are now snapped to the map

• The order in which events are sent to OlCesium is correct, and shapes are no longer duplicated
