Accessing amber from elsewhere than localhost

You have to start the server with the --host argument like in

./bin/server --host 0.0.0.0  (Amber version <= 0.11)

./bin/amber serve --host 0.0.0.0 (Amber version > 0.11)

if you want to listen on any IP address.

By default the server now only listens on localhost for security reasons.
