s-c-mouse and synaptics

[Paul Nasrat <pauln truemesh com>]

I'm starting to think about system-config-mouse changes required for synaptics
touchpad driver support.

Writing the initial config is fairly straight forward, but there are an awful
lot of tunable parameters (potentially doable in realtime with synclient).

Should I aim initially at just detection/default setup and then should people
require it later we can look at having touchpad parameters configurable via
s-c-mouse.
