- added Conjugate() and Rotate() to aiQuaternion
 - SkeletonMeshBuilder can now start hierarchy construction at a given node
 
MD5
 - MD5MESH and MD5 anim now working.
 - MD5ANIM files can be loaded without corresponding MD5MESHES
 - Config option to prevent automatic loading of MD5ANIMs 
 - WIP version of MD5CAMERA support.
 - added test files. No anim test file yet.

BHV
 - fixing formatting 

LimitBoneWeights
 - prints now statistics to the logging system 

Viewer
 - does now specify the LBW post-processing step.
