Corrections in how to access pads terminals in Katabatic/Kite. 

* Change: In Katabatic, in GCellTopology::doRp_AccessPad(), if the supporting
    RoutingPad is big (more than two pitch), do not put the access
    contact in the center but on the edge. This is to avoid cut violations
    between the VIAs and the matrix of VIAs that may be generated under the
    RoutingPad itself.
* Change: In Kite, in TrackSegment destructor, if the legnth of the wire,
    without extensions is less than one picth, enlarge it so it encompass
    it's source & target VIAs (to avoid notches).
* Bug: In Kite, in Track destructor, the TrackElements where detacheds,
    but not deleted, causing a memory link.
