Baseline

Set of changes in order to convert code to modern code and also add mouse input/touchscreen management (could be probably improved).
We can discuss about each change if you want to know why.
Also I have some auto indentations so, Many lines are changes but in fact it is just the same code.

You may want to check the artifacts, the menus are broken, the button popups as well, and the score is not updating.
Unless it's only for me ?

No no it is probably on my side because I chopped in little pieces the code, removed some out of scope parts for the training in order to reduce the complexity, then I rebased on your recent changes and that make a tone of conflicts I solved them but I probably forgot to add what I did removed.
