Changes: Added a preferences menu for FOV and sensitivity!

My discord is 𓂀𝐛𝐫𝐮𝐧𝐨𝐬𝐭𝐞𝐧𓂀#4314, please DM me if you find a bug or just to give feedback. This is the very first demo and it is purely to test how people like the movement before I move on to other things. You may notice that it looks nice as well, thanks that's what I was going for :3
