Tweaked the logic of parachutes to be more modifiable. There now is an upper bound percentage and lower bound percentage which will be applied if you are driving faster and slower respectively. Also added those values in stk_config.xml to make playtesting easier (ticket #1135)

<!-- friction is the friction increase when a parachute is attached.

done-fraction is the fraction of speed when lost will detach parachute -->

lbound-fraction is the lower bound fraction of speed when lost will detach parachute
ubound-fraction is the upper bound fraction of speed when lost will detach parachute
max-speed is a factor that decides the impact of rate of speed (distance between bounds) -->

<!-- time is the time till a bomb explodes. time-increase is the time added
to timer when bomb is passed on. -->
