* ./hurricane/src/viewer:

- Bug: In NetlistWidget/NetlistModel, suppress the "forceRowHeight()"
        method which was terribly slowing down the table display. Instead
        uses the "setDefaultSectionSize()" of the vertical header to setup
        the row height (much more compact display).
    - Bug: In NetlistModel, strangely, although we have a "data()" and a 
        "headerData()" method, the "data()" is also called for the headers
        potentially erasing any previous setting done with "headerData()".
          This was occuring for the fonts settings. Don't known if it is
        a bug or a feature of Qt...
    - Thoses changes has to be ported to the others widgets some times...
