Create big picture diagram outlining complete functionality of both GUI and Patcher engine about patcher

[Desymoo]

Sadly it's too big to link an image too, so I will put a read-only link here instead :) Remember to "open with" draw.io so that you can actually zoom in and navigate the diagram too!

Again, this can and most likely should be reopened at any time to make changes or updates, especially to add the names of the methods in charge of executing the functionality bits :) But for now, done!
