Message:

#2706:

• Added or updated similarity calculators and population similarity analysis for several problems (BinPacking, LAP, Orienteering, Parameter optimization, PTSP, QAP, TF, TSP, VRP)
• Made TSPSimilarityCalculator obsolete since it's essentially the same as the one in the permutation plugin
• Made QAPPopulationDiversityAnalyzer obsolete as it is replaced by the newer PopulationSimilarityAnalyzer
• Removed genotype specific similarity code in QAPPermutationProximityCalculator (again identical to the permutation plugin)
• Changed QAPSimilarityCalculator to perform phenotype similarity instead of genotype similarity (has not been previously used)
