Bug fix: Never slacken a segment from a Pin. 

* New: In Anabatic::AutoContactTerminal, new method "isOnPin()" to
    know if the terminal contact is on a Pin. Introduced in base
    class.
* Bug: In Anabatic::AutoHorizontal::_canSlacken() & AutoVertical,
    forbid slackening from a Pin. As Pin are all on the side of the
    cell (aligneds) and the perpandicular segment will be locked on
    the Pin, it generates intractable overlaps for the router.
