Pull Request description

This adds a new favourites mode, turn it on in settings highlight a game hit R3 and it will add it to the favourites page (or remove it if its already on there) and create a file on cwd so your list saves for subsequent boots.. adding another mode to enable in settings pushed stuff off screen so I had to add scrolling to the dialog windows.

Personal note: I know I have a bit open atm which may lead to some conflicts but I really need to get back to having my full focus on my studies so I've opened everything I've been working on recently and that works, if you want something take it; if there's conflicts later I can likely spare a few minutes to fix it or someone else is welcome to do so but for now I wish you all well and will see you another time :-)

Best regards

force pushed to fix some codacy warnings, the rest are false positive imo.. memalign to 64 bytes works better for ps2 than malloc afair from what sp193 told me years ago
