Another big cleanup, thanks to transform recode. Could do this stage

because Martin recoded the Mirror().

- removed old globals like 'tottrans' or 'centre' or 'centroid' as used
  by old transform
- removed a lot of code from editobject.c
- moved all transform related code to transform_conversions.c
  (Note for Martin; sorry that's a mess... it now has all the weird
   functions for finding posemode dependencies... thats for the depgraph
   phase to remove)
