SilverStripe syslogger sends each line of formatted JSON separately

E.g.:

{
  "foo": "bar",
  "bar": "baz"
}

Each line of this would get sent individually via the syslog to Graylog, making it super difficult to track anything down.

We may be able to remove pretty printing to consolidate into single line logs, e.g. from API responses in the module rating system.

I can't reproduce this locally any more, so I'm going to close.

We can pass true as the third argument to LineFormatter to ask Monolog to handle multi line text messages for us, but it doesn't seem to make any difference to whether the lines get split up or just formatted a bit more nicely on my local machine, so I don't see value in making a PR for it right now.
