0028880: Modeling Algorithms - add missing BRepFeat_SplitShape::Right() getter

- Added Right() method to BRepFeat_SplitShape;
- Added an option in command buc60854, which allows to select Left() or Right() method;
- Modified method BUC60854 in QABugs_14.cxx;
- Added new option to the help of command buc60854;
- Modified test case buc60854. Now its state is "OK";
- Added check Right() in buc60854 test case.
