Changeset 17417 for branches/3026_IntegrationIntoSymSpace/HeuristicLab.JsonInterface.OptimizerIntegration/ViewModels/ArrayValueVM.cs

#3026:

• added initial VM (ArrayValueVM) and control for array values (JsonItemArrayValueControl)
• new types of JsonItems for better type safety:
  • for arrays: DoubleArrayJsonItem, IntArrayJsonItem, BoolArrayJsonItem
  • for matrix: DoubleMatrixJsonItem, IntMatrixJsonItem, BoolMatrixJsonItem
• refactored ValueTypeArrayConverter and ValueTypeMatrixConverter -> better type safety with new JsonItems
• enhanced StringValueVM and implemented JsonItemValidValuesControl with MVVM architecture
• the VM of JsonItemBaseControl is now protected (was private)
• improved JsonItem<V,R> -> now handles JTokens correctly
