Improves the handling of summary vector names by splitting the name and suffix (e.g., difference or history identifier) into separate components.
Make sure the stepping works the same way both for "Step Next" and "Step Next and Add Plot"
Do not show the extension H for available summery vectors in toolbar for source stepping. Make sure that curves with "NAME"H and "NAME"_DIFF will be modified when the summary vector "NAME" is changed.
* Add category WELL_CONNECTION
