7a2a98078a Fixes for broadphase/paircache determinism. 
Revert definition for ATTRIBUTE_ALIGNED16, and try to force sizeof(btSolverConstraint) by using unions with btScalar, for non-btScalar data types.
Use btAssert and not assert.
Don't access btAlignedObjectArray elements, for zero sets

It is off by default, so the existing code should work as before

cf751f5493 Add a convenience method to control the number of single-shot contact points for convex-convex collision detection, using the perturbation method. 
(btDefaultCollisionConfiguration::setConvexConvexMultipointIterations)
Default value is zero, for best performance.

2162f6663d disable help text by default in AllBulletDemos (text slows down many graphics cards) 
improve CollisionDemo.cpp, show multi-contact generation using perturbation
improve ColladaConverter: add hinge/point 2 point constraint conversion support, add btScaledTriangleMeshShape support
Fix Dynamica MayaPlygin: remove 'active' flag, it has to be replaced by mass=0 for active, mass<>0 for passive
Added missing projectfiles
Fixed single-shot contact generation. it is disabled by default to improve performance
Bugfixes for character controller, thanks to John McCutchan for reporting
Constraint solver: better default settings
btDefaultAllocator: aligned allocator uses non-aligned allocator (instead of directly malloc/free)

0754876d77 Calculate multiple contact points (for convex-convex and convex-plane) when less then 3 points exist in the persistent manifold. 
Uses the normal pertubation method, described by Gino van den Bergen:  http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=4&t=288&p=888#p888

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;

0e3b04d952 Add COLLADA physics support for GImpact (allowing dynamic moving rigid bodies using concave collision shapes) in ColladaDemo, and ColladaConverter (import and export) 
Note: ColladaConverter will export a btGImpactConvexDecompositionShape the same as a btCompoundShape, so importing an exported btGImpactConvexDecompositionShape (roundtrip) creates a btCompoundShape
