Change default binding to 0.0.0.0

Pull #54 permits changing the default bind address. The default was
127.0.0.1. This prevents external access unless a command line switch is
used. Since many users of dump1090 are using dump1090 as remote receiver
heads for programs such as plane plotter, this is undesirable. If you
want to lock down your RPi for local use only then use the command line
switch. If not, retain legacy open mode by binding to 0.0.0.0 by
default.
