#1663

• Added an *Operators* parameter in Problem
• Adapted KnapsackProblem, OnemaxProblem, SingleObjectiveTestFunctionProblem, TravelingSalesmanProblem, and VehicleRoutingProblem to derive from SingleObjectiveHeuristicOptimizationProblem<U, V>, renamed and marked old list as obsolete. Note that QuadraticAssignmentProblem, as well as the new DataAnalysisProblems already derived from that class. ArtificialAntProblem was not yet modified.
• Added some test lists and adapted SamplesTest
• Added plugin dependencies that the unit test was complaining about
