[ODE] Plane-Cylinder collision: not good in 0.7, worse in SVN :(

[Bram Stolk]

For me, cyl vs plane is OK for both geomoffset and trf geoms.

Could you please do this test against svn-tree?

- Run test_boxtest and press 'y' a few times.

- Edit test_boxstack.cpp and change line 94 to:
#define USE_GEOM_OFFSET 0
  Rebuild, and re-run the test.

For me, both cases are OK.
I just tested this with current svn, on linux, with double prec.
