Add machinery for cluster persistency

• Adds the surrounding machinery to convert between different types of clusters (including VPMicroCluster, VPLightCluster, UTHitCluster).
• Adds the v1 -> v1 track refitting of a Track::Range in PrKalmanFilterTools (probably suboptimal...)
• Generalizes the VeloIDOverlap relations to other subdetectors
• Fixes the sorting of VPLightClusters (closes LHCb#350 (closed) )

In addition, fixes the missing setting of the fractionx, and fractiony in the converter of PRVPHits to VPLightClusters
