Fix crash when removing pie series from chart...
Fix crash when removing pie series from chart Connections cleanup in PieChartItem destructor didn't account for the possibility of series already having been destroyed. Changed m_series to QPointer so that it'll notice when series gets destroyed, and also added cleaning of slices to series destructor.
