Modify the default rsyslog configuration for V7 servers.  The new
configuration creates a separate queues for writing to the local disk
and sending to the remote syslog server.  This prevents messages from
being lost when the central server is down and allows writing to local
disk to continue.

Change the handling of the use_syslog_conf variable in the
rsyslog.conf.erb template to allow the variable to be either a string
or a boolean.  This works around a problem with puppet's handling of
booleans in some situations.  (whm)

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.
