[ODE] Apparent bug in geom.cpp (v0.03)

well okay, but in ODE i define a plane as:
  p[0]*x + p[1]*y + p[2]*z = p[3]
not as
  p[0]*x + p[1]*y + p[2]*z + p[3] = 0
so you see the sign on p[3] is reversed. confusing huh? i not sure why
you've needed to change dCollideBP() to make it work - but i'm 
reasonably sure that the initial depth calculation works - at least 
i've never see a problem...

hope this helps.
