add newline for line endings. surprised this has not been reported before
update to presume_innocent setting handling if max auth queue reached.

The setting was not getting to be checked if the queue limit was getting reached, so now
we have a flag for skipping auth if queue limit reached.  Only url auth sets this flag for
now.

This is more for cases where incoming listeners are assessed but not denied for any reason.
The listeners still go through the auth queue even if the url engine has been stopped for
N seconds, which should be fine in cases where the service becomes inaccessible.
