Add Custom Loop Normals to Data Transfer.

Titles says everything, just two notes:
* We have to actually transfer plain *normals*, not 'compressed' clnors,
  so had to add pre/post process to transfer to make the conversions.
* Also added interpolation and advanced copy/mixing to CD_NORMAL, for same reasons.
