Trigger siren API for devices

[igoooor]

Something quite easy to implement would be to allow to trigger the siren of a device.
You just have to call "/siren_on" & "siren_off" to control its state.
I tested it with a camera and it works like a charm

@jimhigson would it be possible to implement this?

This repo is no longer being maintained by @jimhigson. I suggest you take a look at my Ring api over at https://github.com/dgreif/ring, which does have the siren on/off implemented
