Remove out-of-date::server.  This is only used on a single host, so
all of the files and Puppet manifest have been moved to the Puppet
model for that server.

error: ssh_msg_send: write appears to be from a network connection
error.  It was logged on git.stanford.edu.  I don't think we care
about it.

The new version of remctld changes some of the logged error messages.
Update the filter-syslog rules accordingly.

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