Introduces a new user interface that looks much nicer, is easier to navigate with controllers, provides more context to users, and is scalable. Some additional features are included. * Adds 'popup menu' with actions that can be used easily from controller * Adds 'main menu', unifying other configuration dialogs * Adds port-forwarding user interface * Adds screenshot feature * Adds volume control feature * Adds gamepad auto-bind option * Adds vsync configuration option * Adds auto UI scaling * Adds preferred window size selection * Adds AV pack selection * Exposes some existing config items in GUI
