DiscretDynamicsWorld.SetGravity's disabled gravity test is inverted

[GoogleCodeExporter]

In DiscretDynamicsWorld.SetGravity:

  if (body.IsActive() && ((body.GetFlags() & RigidBodyFlags.BT_DISABLE_WORLD_GRAVITY) != 0))

should be

  if (body.IsActive() && ((body.GetFlags() & RigidBodyFlags.BT_DISABLE_WORLD_GRAVITY) == 0))

so that objects which have gravity enabled are actually updated, rather than 
the opposite.
