No multitouch on Lenovo Thinkpad E431 synaptics touchpad

[hellslinger]

I understand that this may be a newer Synaptics touchpad which doesn't have published docs to make this work right. Being that the "Synaptics Capabilities" line of xinput --list-props doesn't match the one in:

https://wiki.ubuntu.com/DebuggingTouchpadDetection

I decided to file this report in the hopes it is a minor change to get Multitouch working.

This system has a big "clickpad" and no separate buttons. This notebook also has a trackpoint device (nub joystick).
