Add documentation and more config options to tyre-smoke effect.

Browse source 
Make vspeed/diff_norm configurable. Allow effect to be independent of
vspeed, so it works for all gear (after main gear touch down, vspeed is 0,
so smoke effects for nose-gear usually wouldn't work).

# auto: 1 when tyresmoke should start on update loop. 0 when you're going
# to call the update method from one of your own loops.
#
# diff_norm: value adjusting the necessary percental change of roll-speed
# to trigger tyre smoke. Default value is 0.05. More realistic results can
# be achieved with significantly higher values (i.e. use 0.8).
#
# check_vspeed: 1 when tyre smoke should only be triggered when vspeed is negative
# (usually doesn't work for all gear, since vspeed=0.0 after the first gear touches
# ground). Use 0 to make tyre smoke independent of vspeed.
# Note: in reality, tyre smoke doesn't depend on vspeed, but only on acceleration
# and friction.
