solution for cars behaving strangly when they get airborn on a curb or hill

I determined that this  problem was caused by stale bot code on my 
system. (I hope i did not waste your time on this problem,  Christos.
If i did, you  have  my  sincere  apologies)

The problem with the levitating car at the start of the race is still
there, however.

I  have  been  doing  nothing  but  working  on  torcs  for  the  last year
and  a half. My changes are spread all over the place. I can't just 
replace my version of torcs, i have to carefully merge the changes
in 1.3.1 into my version of torcs.
