  Log:
  Fix for bug #5250: inaccurate conversion between edit and pose mode bones.
  
  Using acos(dot(u, v)) to find the angle between two vectors is quite
  inaccurate, and there's a better way to do it, as explained here:
  http://www.plunk.org/~hatch/rightway.php
  
  Also changed the use of atan for computing roll to atan2 in some places,
  the latter avoids accuracy and division by zero issues.
