Reworking of joystick support :

- Joystick type now selectable
- Added emulation of standard joysticks with up to 8 buttons
- Added emulation of Microsoft Sidewinder pads
- Host->emulated joystick button & axis mapping now configurable (only on Windows atm)
- Gameport registers now take 1us to access - helps Sidewinder drivers
