* Updated journalPrefix value definition to follow the standard.

there is no need for it in this script.
* Removed display of current SiteTags from '-man' output as it won't generate relibly for AsciiDoc.
* Removed '-ssh_opts' and '-skip_ssh' flags from doc.

installed version). [A future full setup may be added relying on the Helix Installer.]
