New Features:

* Graphical simulation result is displayed in a table view to show
  run-time and overlap information if the corresponding processors
  are loaded. The Simulation result dialog can be deactivated in
  the preferences.
* PedestrianOverlapProcessor returns two values "distance", "overlaps"
  for each overlap detected. If no overlap occurs the output is empty.
  "distance": The distance between the center of the two pedestrians
  "overlaps": The amount the two pedestrian overlap

Changes:

* New version for scenario.json (0.5):
  - remove scenario/attributesSimulation/needsBoundary as it is not
  used anymore.
  - remove attributes from processor PedestrianOverlapProcessor because
  the radius of a pedestrian can be retrieved from the topography at
  run-time. This would allow to detect overlaps of different sized
  pedestrian in the future.
* Helper interfaces for testing:
  - The TestResourceHandler interface groups all methods
