Description
The external evaluation problem as of r3865 is close to a user defined problem, but has a special evaluator and a driver parameter. It would be good to extract the generic parts and implement a user defined problem that can be used to quickly prototype a new problem.

One problem with the current implementation of UserDefinedProblem is that its Evaluator is initially null. Unfortunately all of the Algorithms assume that Problem.Evaluator is not null, so there are some NullReferenceExceptions flying.
I can see following two solutions:
- Either change all the algorithms to include a null-check on Problem.Evaluator before using it
- Or create a dummy evaluator (in HeuristicLab.Optimization)

- Added EmptyUserDefinedProblemEvaluator and set as default evaluator in UserDefinedProblem
- Reverted accidental change to ES

The user defined problem has been implemented. Further changes and requests should go into separate tickets.
