[syslog-ng] include file syntax

[Evan Rempel]

I think that you should stay with the full syslog-by syntax with the  
{} because you may want to add options to the statement in the next  
version and the simpified syntax does not allow for options.

Perhaps an option of "optional" so that if the file did not exist  
syslog-by would continue without it. Other options may become apparent  
over time.
