i should have released this much sooner: crane.exe ~3.5mb

things to note:
- i was relatively new to gamestudio and its physics engine when i created this more than 4 years ago. probably i would code some things a bit differently now and of course i would also do better models.
- the physics engine changed in the meantime (newer versions of ODE and other tweaks). physics behaves slightly different now and the crane simulator would need some tuning to get it working like with the first a6 release again. currently the crane shakes a lot at the beginning and then it leans back too much. i hope the problems can be easily fixed again.
