Subject: [PATCH] [doc] preproc: translate {{INSTALL_PREFIX}}

preproc.sh now translates the {{INSTALL_PREFIX}} string as well as the
{{OWLPS_VERSION}} string. Both values are now obtained from the
corresponding environment variables (OWLPS_VERSION was previously
obtained through a special git command).
