Improve logging and change default .d dir

Rather than looking at the environment varible otherwise use the local
automv.d directory - set it to something more centralized in the
environement e.g /usr/local/etc/automv.d/

Also the logs were unclear what was happening so extracted the find
query into a function to be able to run/rerun it a few times to improve
the existing logging. I wonder if there is a better way to print what is
happening in the xargs w/o repeating the move a bunch:
        fn_mv {
                echo "Moving: $1 to $2"
                mv $1 $2
        }
        and call:
        find ... | xargs -I'{}' fn_mv {} $target

Perhaps?
