90f96aec27 Introduced btActionInterface. This makes it easier to extend user-defined actions, such as vehicles and characters. 
btRaycastVehicle and btKinematicCharacterController are derived from btActionInterface now.
Some cosmetic cleanup: changed sourceforce/sf.net url to bulletphysics.com.

459c22e7cb Synchronized changes of Bullet, from Blender. 
Added optional flag btSoftBody::appendAnchor(	int node,btRigidBody* body, bool disableCollisionBetweenLinkedBodies=false), to disable collision between soft body and rigid body, when pinned
Added btCollisionObject::setAnisotropicFriction, to scale friction in x,y,z direction.
Added btCollisionObject::setContactProcessingThreshold(float threshold), to avoid collision resolution of contact above a certain distance.
Avoid collisions between static objects (causes the CharacterDemo to assert, when a dynamic object hits character)

5be9f8f301 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.

210fe36106 Add backface culling and option to keep unflipped hit normal in case a ray hits a back-facing triangle. 
Usage: set RayResultCallback.m_flags to kF_FilterBackfaces, optionally combined with kF_KeepUnflippedNormal.
Thanks Andy O'Neil for the patch!

Remove the force_inline for some internal constraint solver methods, it makes re-use easier.

cf751f5493 Add a convenience method to control the number of single-shot contact points for convex-convex collision detection, using the perturbation method.

bcbe730471 Perform several rotation pertubations, to create multiple collision contact. works for convex versus plane. todo: convex versus convex. 
See issue http://code.google.com/p/bullet/issues/detail?id=20:

Note that the default number of pertubation iterations (10) and pertubation angle (0.05) can be modified through the collisionConfiguration:

	btConvexPlaneCollisionAlgorithm::CreateFunc* func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(BOX_SHAPE_PROXYTYPE,STATIC_PLANE_PROXYTYPE);
	func->m_numPertubationIterations = 0;
	func = (btConvexPlaneCollisionAlgorithm::CreateFunc*)collisionConfiguration->getCollisionAlgorithmCreateFunc(STATIC_PLANE_PROXYTYPE,BOX_SHAPE_PROXYTYPE);
	func->m_numPertubationIterations = 0;
