#2174: Worked on programmable problem

• Changed ProblemBase to IProblemDefinition and SingleObjectiveProblemBase to ISingleObjectiveProblemDefinition
• Derived ParameterVectorCreater, -Crossover, and -Manipulator from MultiOperator<> instead of InstrumentedOperator
• Split the megamoth ScriptOnInstanceChanged to multiple methods dealing with single-vector and multi-vector encodings separately, it's still a lot of tedious code
• Removed maximization from Configuration again (would not be consistent with multi-objective problems)
