Feature/json parser (#18)

* chore(model/json-parser): Added maven dependency
* chore(model): Removed old test JSON file
* refactor(model/GameState): List better then map, entities should be able
to overlap

* feat(Pacman): Added GameState builder to initiate GameState with given
paramters.

Added a short example JSON-file, more key-value pairs needs to be added
as the game progresses.
Likewise the builder won't parse for any other key-value pair
automatically.
