- Modified collective drive operations to run motors in individual tasks

  scriptchain of a node to finish.

- Made histmemsec dim and rank manager privilege. To allow chnage at runtime.
  Is required for SANS
- Fixed some issues with multicountersec, mostly relating to passing things through
  in a sensible way.
