The original method of overriding the use of /etc/syslog.conf failed
because of a duplicate declaration of the file resource.  This
restructuring should solve that problem.

This change does not affect the current usage of the module.  It does
allow manifests to choose to retire /etc/syslog.conf in favor or
fragments in /etc/rsyslog.d to control the syslog activity.  One
default fragment, 90-local.conf, that writes syslog messages
locally.

This change also include a fragment define that is used for the
management of rsyslog fragments.

This is the (old) master branch along with the fixes to the
cron file permissions that Russ made.
