main.cpp: create sfml window

I created some useful classes 
Logger.h/cpp: Logger class which uses SFML clock and vprintf to print message into stdout 
GameController.h/cpp: Class which is used to measure time and contains reference on window class 
GameState.h/cpp: A parent class for every game's state. It uses GameController to measure time.
