Some optimizations for btHeightfieldShape, thanks to Danny Chapman
Quick check on AABB (was not done) and reduce calls to 'getVertex'
fix some crash in btSoftBody, related to running out-of-memory. You can configure the default maximum memory allocation for the signed distance field using worldInfo->m_sparsesdf.Initialize(hash, maxAllocation);
fix 'exploding' btSoftBody, related to very small masses. You can configure maximum displacement per frame using worldInfo->m_maxDisplacement
avoid some crash in the world importer
In some degenerate cases the contact normal is pointing the wrong direction
so fix it now (until we can deal with all degenerate cases in GJK and EPA)
contact normals need to point from B to A in all cases, so we can simply check if the contact normal really points from B to A
We like to use a dot product of the normal against the difference of the centroids,
once the centroid is available in the API
until then we use the center of the aabb to approximate the centroid
