TicTacToe project init
First try on GoF Observable pattern in Rx
Added Game + Board model (Game n.y.f.)
Modified code and added GameState functionality
Added controlling methods to Game and made other methods for GameState
Made full working UI
Added fully working controller (in Rx) for TicTacToe
Rewritten part of the BoardController using lambdas
Deleted unused folders
Fixed the bug that when clicking on an already filled item, the current
player switched.
Changed buttons to be handled via a ActionEvent instead of a MouseEvent,
so that also the spacebar is able to control them.
Added new GameState to the game: Draw
