Message:

#3026

• removed the option to set the value for JsonItems via exporter
  • reworked some base controls
  • added new controls for JsonItem specific properties (e.g. ArrayResizable)
  • deleted a lot of obsolet controls
• removed the Enable checkbox in the detail view of JsonItems
• exporter now clones the IOptimizer object
• added a check + message for unsupported exports
• list of JsonItems now includes unsupported JsonItems (disabled and marked with 'unsupported')
• refactored the converter type check
  • now every converter has to specify its supported type(s)
