If the getTargetId TraCI-Command is executed with the targetId "-1" (invalid for any agent) then the command returns a list of all targetIds currently in the simulation.

Bugfix in "TargetChangerController": "useStaticTargetForAgent()" did not update agent's "nextTargetListIndex" properly

issue#277 fix synchronization problem where the OnlineVis InofPanel is out of sync with the OnlineVis model.

Also fixed incomplete initialization of mock objects
in method "createTwoTargetsAndTwoPedestrians()".

remove fine tune condition in brute force

Closes #278

See merge request !90

In "OSMBehaviorController", fixed severe bug in method "findSwapCandidate()" and added TODO comment to write unit tests

[GUI] Visualization: make interpolation configurable.

In "Pedestrian", encapsulated psychology-related attributes into new class "AttributesAgentPsychology"

Also updated "TargetVersionV1_5" to reflect this change.

In "PostvisualizationModel", visualize content of "mostImportantStimulusCol" and "socialCategoryCol"

Renamed "FootStepMostImportantEventProcessor" to "FootStepMostImportantStimulusProcessor" and extended JSON transformation

Also, moved two long-running scenarios to "Scenarios/Demos" to shorten
the integration test phase of Vadere.

Potentials for cellular automaton - no repulsion from walls / other pedestrians - only high values at other pedestrian's positions and at obstacles.

Also renamed state package "psychology.stimuli" to "psychology.perception".

Also renamed following classes:
- "EventCognition" to "StimulusProcessor"
- "SalientBehaviorCognition" to "SalientBehaviorProcessor"
- "EventController" to "StimulusController"

Watch out: Event output processors and also the existing scenario files
have not been migrated. Therefore, the unit tests fail at the moment!

Also, deleted dummy test files for renaming "event/events" to "stimulus/stimuli".

Two aspects are missing so far:
- Writing a migration to rename nodes in JSON representation.
- Rename controller classes and unit tests.
