Console mode for multiple game automation (#2777)

* Remove ruleset from GameSetupInfo class

* Remove dependency from Gdx for file IO:
- load Ruleset
- save/init in GameSettings
- get settings in GameSaver

* Remove simulation logging from GameInfo class

* MapGenerator: add switch for RNG seed verbose

* PlayerPickerTable small refactor

* Basic console mode

* Add multithreading to console mode and refactoring.

* Merge branch 'master' into console

* Small refactor
