* ./hurricane/src/hviewer :

- Bug: redraw the palette layer samples whenever the style changes. Uses a
        new, more clear model to transmit signals. A star model where the
        CellWidget is the center, signals propagate a void pointer which tells
        the emitter to avoid looping. First a slave emit the signal to the
        CellWidget. When the CellWidget receive the signal it's transmitted to
        all slave widgets.
    - New feature: ExceptionWidget (derived from QDialog) to display properly
        catched exceptions. The Abort button of the Dialog forces the program
        to core-dump with a SIGSEGV. The "Try to Continue" resumes the program,
        which is higtly to crash anyway...
    - New feature: a HApplication in replacement of the QApplication to catch
        exceptions in the notify() function, that is exceptions that could be
        throwed inside event handlers.
