Changeset 17404

#3026:

• fixed a bug in BaseConverter -> the range for percent values should be returned correctly now
• fixed a bug in ConstrainedValueParameterConverter, ParameterizedItemConverter, ValueParameterConverter -> unsupported json items get filtered now
• JCGenerator is now a dynamic class and can return all JsonItems for an IOptimizer now (instead of string only) + it is now possible to generate an template string with an IEnumerable<JsonItem>
• added first version of an export dialog for JsonInterface
  • it is organized with a main view (for the dialog) and some user controls (for a better visualization of an JsonItem -> to reduce wrong user inputs)
  • the user controls inherit a base control, which organizes some base values of an JsonItem
