Use sort by name by default

Some interfaces IP address may change over time, making it harder to process outputted data. If data is ordered by name, the json can be parsed perfectly in child systems.

Hi - this is a fairly simple patch, but I'm reluctant to change default behavior without a way that allows developers to get-back the original behavior - for example you could pass a $sort parameter into function gateway_status
