+ fixed issue related to temporary/root collision shape in btCollisionObject

Browse Source 
+ normalize plane normal input for btStaticPlaneShape
+ fixed issue related to swapped collision detectors (SphereTriangleDetector in particular)
Thanks a lot to Andrey Tuganov for reporting the issue and his reproduction case ( http://www.bulletphysics.com/Bullet/phpBB3/viewtopic.php?f=9&t=2143 )
