[ODE] Box/Trimesh contact filtering and oblong geoms

[Rodrigo Hernandez]

The checks for dEpsilon need to be added to the old configure method, 
just add

#define dEpsilon FLT_EPSILON

if using single precision or

#define dEpsilon DBL_EPSILON

if using double precision to the generated config.h

Or if you're on anything but Visual C++ on Windows, use autotools, 
instructions are on the INSTALL file.
