add initial support for soft body / cloth serialization, and updated SerializeDemo to load soft bodies/cloth.
...
Serializes soft body nodes (vertices), links, faces, tetrahedra, materials, anchors with rigid bodies.
Some todo's are serialization of pose, constraints between soft bodies

basic implementation of self-collision for btSoftBody with collision clusters: perform regular soft body versus soft body, but disable collision detection between clusters that are connected/share any node (vertex).
...
currently self-collision is always enabled for soft bodies that use clusters collision detectoin. to disable, call 'softbody.m_clusterConnectivity.clear' after 'generateClusters(...) call.
