Add ruby-syslog-logger package version 1.6.8.

Logger::Syslog is a Logger replacement that logs to syslog.  It is almost
drop-in with a few caveats.  You can add Logger::Syslog to your Rails
production environment to aggregate logs between multiple machines.

NOTE! You can only set the Logger::Syslog program name and facility when you
initialize Logger::Syslog for the first time.  This is a limitation of the way
Logger::Syslog uses syslog (and in some ways, a limitation of the way
syslog(3) works).  Attempts to change Logger::Syslog's program name or
facility after the first initialization will be ignored.

This particular Logger::Syslog improves the original by correctly mapping
Rails log severities to the Syslog counterparts.  It also adds the ability to
select a syslog facility other than "user."
