two finger scroll added to synaptics

[Brett Lymn <blymn%internode.on.net@localhost>]

Folks,

I have just added code to the synaptics driver to support "two finger"
scrolling.  If the finger width is detected to be in the specified range
then any y motions will be translated into z-axis events which emulates
the behaviour of a mouse scroll wheel.  By placing two fingers side by
side on the trackpad you should get scroll events instead of mouse
events.
