Joystick name

This changes the joystick to /dev/input/rumblepad. The reason for the change is that after installing Ubuntu 12.04 64bit, the joysitck became /dev/input/js0 not /dev/input/js1. So I have created a udev rule to make it always /dev/input/rumblepad.

To use, copy the udev file to /etc/udev/rules.d/, remove and replug joystick dongle.
