Moved psychology-related attributes to own JSON node "attributesPsychology" and display these attributes in an own tab in GUI

Implemented "TargetVersionV1_7" to reflect this change in the JSON file.

- Renamed "AttributesPsychology" to "AttributesPsychologyLayer".
- The new class "AttributesPsychology" is now the wrapper to hold
  all psychology-related parameters. The existing psychology parameters
  from "AttributesSimulation" moved to this class.
