* When you switch from mempak to rumble , rumble pack is never initialized.
* Rumble stops working after loading a savestate.
* No shortcut working when you have 4 xinput controller plugged.
There is a performance hit when you check for a controller that wasn't attached last time you called it.
This fix minimizes a performance issue with XInput on Windows when checking for a disconnected controller.
If you get ERROR_DEVICE_NOT_CONNECTED from XInputGetState, you shouldn't call that slot for a little while.
This is to stop XInput controller one from having to be used in first player.
Also remove the need for the bconnected variable, allows controllers that are connected at game start to be disconnected and reconnected for XInput.
