- fixed #24. The game itself is not listenable anymore. Instead,
instances listen to the new PlayingGameState for ticks
- added one additional state (main menu dummy), which can be accessed by
pressing the start-button (currently: M)
- swapped some functionality around in more intuitive places: the logger
does the loading of flags from a file itself (instead of having a static
method in the game) and the configuration itself notifies interested
objects when it is being reloaded (interested instances have to
implement IConfigListener)
