Changed the StripToolPlot::addSeriesToPlot(...) and StripToolPlot::removeSeriesFromPlot(...) methods to return a boolean indicating its success/failure. Changed the StripToolModel::contains(StripToolPV *toMatch) to a const function. Replaced the loop iterating over the characters in a pv name in StripToolModel::savePVData(...) with the QString::replace(...) method.
