In Cell, separate flattenNets() and createRoutingPadRings(). 

* New: In Hurricane, in Cell, no longer create rings of RoutingPads when
    flattening the nets. Put that functionnality into a separate method
    ::createRoutingPadRings().
      This allow to perform the Net flattening in Etesian *without*
    the rings, which slow it down. Then the rings are created by
    Knik/Kite. This also solves the double ring creation when doing
    P&R of a complete chip (rings where created twice: in the core
    block for Etesian and at chip level for Kite).
* Change: In Etesian, slight beautification of the printed informations.
