[ODE] tri-list and new collision

[Shaul Kedem]

Cool,
 But I am still trying to get everything to work
together under msvc 6... I accomplished compiling ,
writing code for, and adding the stepfast using msvc 6
but I still can't do anything with opcode 1.2 (and
latest ODE from the cvs)

 Please help,

Thanks,
Shaul Kedem.
