    Qt: Column preference fixes.

    Don't call redrawVisiblePackets in PacketList::sectionResized. Otherwise
    we trigger the crash in bug 11179. Call recent_set_column_width instead.

    Clean up the slots called when column preferences change and when recent
    column widths change.

    Update our column visibility in redrawVisiblePackets.

    Use recent_get_column_width when writing the recent file. columnWidth
    doesn't return a valid value when we're not visible.

    Bug: 11179.
