Title: Add a script to build a custom driver which enables middle click scroll with the Trackpoint/Clickpad

Got this script from https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1246683/comments/50 and I thought you might want to have it here. All credit to the guys who wrote the script on that launchpad bug.
