Makes it easy to address bmx7 shorids and hostnames with ping, ssh, etc. Both are stored in /tmp/hosts/ and so loaded by dnsmasq. Instead of using a cron job which triggers the bmx7 deamon every so and so, inotifywait is used to see creation or deletion of originators in /var/run/bmx7/json/originators/ Signed-off-by: Paul Spooren <spooren@informatik.uni-leipzig.de>
