CONFIG: handle string splitting [zsh] (#2640)

- all file-handlers can now be created with a user-specified
  communicator and/or with specified io-ranks. This makes it possible
  to quickly create special file-handlers for subsets of ranks.

  For the uncollated file output this implies that the file-handler
  now has a communicator only with itself, which is correct since each
  rank is acting like it own IO master rank and doesn't coordinate
  effort with other ranks.
