- fixed slow file reading of vertex deform groups.

Browse Source 
found out that per vertex, per deform group, a heavy function was called
  to get an address from a huge array. that address even didnt exist, was
  not written in the file... just removing the code makes .blend file
  reading happy again.

  check it by parenting a 40k vertex mesh, to an armature with "use
  armature" and "create vertex groups". save and load file.
