[ODE] cylinder plane bug

I don't know if it can help but :
- cylinder/plane is ok when encapsulated in a transform geom ...
- the only bad thing i found encapsulating cylinder inside a transform geom
is that sphere/cylinder colide is not good ... Bad contacts points when
cylinder rotation is not ID

Hi, thanks for your fix. To test I hacked test_boxstack to limit the object
count to 5, set the gravity from 0.5 to 5.0 and hit 'y' for a bit. The lack
of cyl-cyl made this job a lot easier :-)
It seems that although it generally works most of the time - there's a
problem when the cylinder hits the plane on a corner at around 45 degrees.
It acts like there's a 'hole' there which causes the cylinder to fall
through the plane a fair amount.
With this fix in place this falling is limited but still wrong - without it
though, I've seen them fall forever :-(
Bram, how can we fix this? :-)
ps. This was in a vs2005 Single build.
