Changes to allow for playing.

Added toString to important classes. Gameplay example in Game.java.

The game currently uses priority and action points, while move order (based on submission) is not tested. Cleaning, commenting, gameController -> serverController return string and some functionallity is not yet done.

There is also a series of minor changes all over to make gameplay executions smoother.

Now verified action order and that collision works. Changed the performTurn function to return a list of actions, changed actions to contain a list of affected tiles. The list of affected tiles have 3 possible values: null if execute has not been called, empty list if no tiles affected or action failed for some reason, list with coordinates if action successfull. Might change null to empty list later, but might be useful to have a way of determening if an action has been executed.

The makes converting results to string easier. E.g. "Movement: [[0, 0]]" can be achieved with String.format("%s: %s", action.getClass().getSimpleName(), action.getAffectedCoordinates())
