The error i created was only a typo in an include statement filename.  so, 
the only error is really a 'file not found' type error.  i wouldn't think 
this would be reason enough to shut down.

Also, there is nothing in my log about the error.  The only time i seen 
the error was on the cli when trying to start radiator back up again.  It 
would be nice if radiator didn't shut down on error, but if it must, i 
would think the last line in the log would be why it shut down.

I guess since it can't parse the config during the startup, it doesn't 
know where/how to log, so the best time to log such an error is before it 
shuts down, while it still has config of where the log file is.
