it's supposed to be an ellipsoid not an egg!

and it isn't very small but has about the same size as the gamestudio character models.
making the ellipsoid smaller seems to fix the getting stuck problems but how could i solve the slope problem then? move_min_z doesn't have any effect anymore with this method since the ascending happens because of the c_trace calculations and not because of c_move gliding. it's possible to move up almost vertical walls. can this be fixed in a simple way? without breaking nice gliding behaviour?
