    Remove default paragraph style from user visible lists.

    Fix sorting of style names.

    The style names were not sorted in natural order.
    Use KStringHandler::naturalCompare to fix the problem.

    The sorting of styles per category (ie. list styles,...) belongs to
    a wish item, and needs debating first.
