This patch adds visualisation of the residuals to QgsGCPCanvasItem (red lines). Also, it removes some members in QgsGCPCanvasItems and adds an association to QgsGeorefDataPoint instead (removes small redundancies between those two classes).

Manuel, could you review this patch?

Marco, thanks for the patch, cleanups and new features looks good :-) I just applied a minor
correction which flips the resiudals y-axis, needed due to the somewhat idiosyncratic coordinate system used for GCP transforms.
