Upgraded to Bullet 2.74. The upgrade introduced a few bugs, which need to be fixed before Blender 2.49.

In particular, the Bullet vehicle seems broken, and some soft-body demos don't work.
No new features or benefits are added yet, but a few improvements are planned before Blender 2.49 release.

Please update the build systems, and add those 3 files:
extern/bullet2/src/BulletCollision/CollisionDispatch/btActivatingCollisionAlgorithm.cpp
extern/bullet2/src/BulletCollision/CollisionDispatch/btGhostObject.cpp
extern/bullet2/src/BulletCollision/CollisionShapes/btConvexPointCloudShape.cpp

I'll watch the Blender mailing list, in case this commit causes some issues.
