- Split the joystick menu into two parts: A top level with general options

and a list of all attached controllers, and a second level for configuring
  an individual controller.
- Fixed: Pressing Up at the top of a menu with more lines than fit on screen
  would find an incorrect bottom position if the menu had a custom top height.
- Added the cvars joy_dinput, joy_ps2raw, and joy_xinput to enable/disable
  specific game controller input systems independant of each other.
- Device change broadcasts are now sent to the Doom event queue, so
  device scanning can be handled in one common place.
- Added a fast version of IsXInputDevice that uses the Raw Input device
  list, because querying WMI for this information is painfully slow.
- Added support for compiling with FMOD Ex 4.26+ and running the game
  with an older DLL. This combination will now produce sound.
