Fix bug & compatibility issues with Qt 5.

* Bug: In Hurricane, in NetlistWidget CTOR, the horizontal header was set
    up assuing that there was (at least) three sections (column) in the
    model, which was wrong. Now it is done in the setCell() method which
    know the exact number of sections.
      It was a bug in both Qt 4 & 5, but was showing only under Qt 5.
