* Always show the mouse cursor when the mouse is disabled

* Rename IN_StartupJoystick to IN_InitJoystick, add IN_ShutdownJoystick
* Add IN_Restart, which avoids calling IN_DeactivateMouse at the wrong time
* Call IN_Restart when changing r_fullscreen
* Add CVAR_ROM r_sdlDriver for easy checking of the SDL driver in use
* Random README tweaks
