Title: Replace optparse with argparse

* Since version 2.7 optparse is deprecated and replaced by argparse. This patch replaces optparse in the given files.
* Also added a small note in nipap.man.rst relating to the settings file.
* In the nipap-passwd tool you can now list a specific user (with option -u).
