Implemented a basic ChoiceWindow

This window should be used when there are a few choices available (such as in TitleScreenGameState and MenuGameState) and one needs to be chosen. The implementation currently is bad, the code is messy and it could be optimized. Plus, there are a few bugs in it and no choice can currently be made, only the rendering has been done.
