#2174:

• Added ISingleObjectiveOperator and IMultiObjectiveOperator interfaces
  • Added interface to all operators that would fall in either of these categories (excluding MainLoop operators)
• Added some checks in BasicProblem on whether the MultiEncoding is being used
  • A new event handler is added that reacts on encodings being removed or added to the MultiEncoding
• Added code to remove the non-fit operators in (Single|Multi)ObjectiveBasicProblem
