A bunch of fixes for node tool from Richard:

- fixed update of node tool vertex markers after undo #1736
- fixed a crash when trying to edit non-existent feature
- vertex markers are now QgsVertexMarker instances (i.e. don't scale when zooming)
- fixed moving of points in point layer
- original node is excluded when snapping

Fixed double map canvas refresh when doing edits.
