readsb: new package
This package is based on dump1090-fa with many modifications. A big advantage over dump1090-fa is that it can connect to multiple services like adsbexchange, piaware or fr24feed. As the idea for this package is mostly to feed other services, the HTML files to serve via a webserver have not been included. The service(s) that will be fed by readsb can offer such a webpage instead. Finally, the init script does not use local variables, as local is undefined in POSIX.
