In "JsonConverter", extended method "deserializeScenarioRunManagerFromNode()" to correctly deserialize events from scenario file.

VadereSimulator/src/org/vadere/simulator/projects/io/JsonConverter.java:
- Also extended --- BUT NOT TESTED --- method "cloneScenarioStore()".

VadereState/src/org/vadere/state/util/StateJsonConverter.java:
- Implemented method "deserializeEventsFromNode()".

VadereState/src/org/vadere/state/util/StateJsonConverter.java:
- Added method "serializeEventsToNode()".

changes:

* move groupSizeDistribution from AttributesCGM to AttributesSources
* rename standardDerivation to standardDeviation in AttributesTimeCost
* update all existing scenario files to version v0.3

The VadereConsole command line tool is know able to migrate old
scenario files to a new version. All old capabilities were moved
to the subcommands project-run and suq. See usage below

usage: Vadere [-h] COMMAND ...

Runs the VADERE pedestrian simulator.

optional arguments:
  -h, --help             show this help message and exit

subcommands:
  valid subcommands

  COMMAND
    project-run          This command uses a Vadere Project and runs selected scenario.
    suq                  Run a single scenario file to specify to  fully controll folder structure for input and output.
    migrate              Run migration assistant on single sceanrio file

In "run_vadere_console_with_all_scenario_files.py", run ALL scenario files, catch exceptions and log exceptions.

Exit with return code 1 if at least one test failed. Otherwise, return 0.

This only affects scenarios which do not us group models. Due to
refactoring of the group model the group size distribution is
set by source. This allows different source to spawn different group
sizes.

VadereSimulator/src/org/vadere/simulator/control/Simulation.java:
- Create "EventController" in constructor and use object in method "updateCallbacks()" to raise events.

VadereState/src/org/vadere/state/events/json/EventInfoStore.java:
- Deleted unnecessary comments.

In method "updateCallbacks()" of class "Simulation", use "scenarioStore.getEventInfoStore()" to raise events instead of "EventFactory".

Notes:
- "scenarioStore.getEventInfoStore()" is filled via "Event TextView".
- "EventInfoStore" object is not serialized to scenario text file at the moment.

In "gui/projectview/view/ScenarioPanel", set "Scenario" for "eventFileView" and added "serializeEvents()" to "state/util/StateJsonConverter".

VadereGui/src/org/vadere/gui/projectview/view/TextView.java:
- In "setVadereScenarioThrows()", populate text field by using new method "serializeEvents()" from "StateJsonConverter".

In "run_vadere_console_with_all_scenario_files.py", print runtime (in seconds) for each scenario file.

Moved CI helper scripts to "Tools/ContinuousIntegration" and enabled Java assertions in POM files and helper scripts.

.gitlab-ci.yml:
- Refactored complete file: moved comment on top of file.
- Call helper scripts in "Tools/ContinuousIntegration" instead of just "Tools".

Tools/ContinuousIntegration/run_vadere_console_with_all_scenario_files.py:
- Execute scenario files alphabetically.
- Use "-enableassertions" when invoking Java.

POM files:
- Use "<enableAssertions>true</enableAssertions>" to be independent of SureFire's default settings.

VadereSimulator/src/org/vadere/simulator/control/Simulation.java:
- Added dummy implementation to raise events using "EventInfoStore" but commented out
  because VShapes are not handled properly at the moment and Jackson throws an exception.

VadereSimulator/src/org/vadere/simulator/projects/ScenarioStore.java:
- Now, this class uses the "EventInfoStore" object instead of a list of events.

VadereState/src/org/vadere/state/util/StateJsonConverter.java:
- Added method "deserializeEvents()".

Each JoltTransformation is create as a Singletone from the abstract
JoltTransformation class. These classes manage the transformation and
postHook processing if needed. All resource files were renamend to
automatically build resources names based on the current version alone.

The package "types" holds the already existing events and "json" handles the de-/serialization of events.

Added two wrapper classes to encapsulate the JSON de-/serialization via Jackson library:
- "json/EventInfo"
- "json/EventInfoStore"

This addition is needed because not all transformation can be done
with the Jolt Transformation. Each implementation of JoltTransformation
has a list of PostTransformHooks which will be executed in order on
the JsonNode representation _after_ the Jolt transformation is done.

This allows context specific transformation. If needed a postHook will
be added in the future.

This reverts commit 7b1da6cf.

The MigrationAssistant know has tow implementation which can be used
interchangeably. The Selection of the the right implementation is
triggerd by a flag within the MigrationOptions Class.
