NFS server edits:

* remove most (not all) passive voice
* remove punctuation on bullet points except those under "Case studies" which are a command parameters with a qualifying sentence.
* some minor wording changes for better understanding (for instance "conserved" becomes "preserves")
* added Serge to contributors
