Drop trackstick emulation mode

Browse Source 
"Trackstick emulation mode? That exists?" I hear you say? Yes, indeed. Well,
no, not anymore. This driver is already unmaintainable without features like
this.

.SS Trackstick mode
Trackstick emulation mode is entered when pressing the finger hard on
the touchpad.
.
The FingerPress parameter controls the minimum required finger
pressure.
.
If the finger hasn't moved more than MaxTapMove after MaxTapTime has
elapsed, trackstick mode is entered.
.
In this mode, moving the finger slightly in any direction gives a
speed vector that moves the pointer.
.
The TrackstickSpeed parameter controls the ratio between pointer speed
and finger movement distance.
.
Trackstick mode is exited when the finger pressure drops below
FingerLow or when the finger is moved further than MaxTapMove away
from the initial position.
