* Removes Linux-specific joystick handling
* Adds cross-platform GLUT joystick handling; Caveats:
- GLUT is not robust to joystick hot plugging like my old Linux-specific code was. (Fix should be made in the
GLUT driver and pushed upstream if we really care)
- Deprecated X11 renderer now can only use keypad joystick
