[SDL] Joystick support (linux)

[Ben Campbell]

I've noticed that SDL on Linux looks for joystick devices at /dev/jsN (where 
N is a number). I've also seen devices at /dev/input/jsN, which are symlinked 
to /dev/jsN on some (most) machines, but don't seem to be on others.

Should SDL be changed to look for joysticks in /dev/input/ as well?
Is there an 'official' place for joystick devices to appear in Linux?

Thanks,
Ben.
