Fixed naming of pitch, yaw, roll thing in rotation that was wrong. Now they are named xAngle, yAngle, zAngle in Spatial and Quaternion. Pitch , Yaw, Roll are just mentionned in the javadoc.

There has been several posts about that, the last in date is here http://jmonkeyengine.org/groups/general-2/forum/topic/confused-about-euler-axes-and-jme-axes/#post-169736
