Add z-wave node ID to Hardware tab in Devices display

[JohnLines]

At present all my z-wave devices show in the Devices display with the Hardware tab showing the Name of the Z-Wave controller from the Hardware display.

It would be useful, particularly for a setup with several Z-Wave devices from the same manufacturer and same hardware type, to show the Z-Wave Node ID associate with that device, as [controller-name][separator][Node ID] - for example Razberry.12 where 12 is the decimal Node ID, or z-stick/x15 for example - the separator should be something unlikely to have been used in a controller name, and I think decimal Node IDs would be better, unless there is a good reason to use Hex, but it should be consistent.

This would be be a useful diagnostic, using information which must be available anyway, and would be particularly useful in the case where Domoticz is a secondary controller which has received some z-wave nodes, and the user wants to match the Devices it has created to real world devices
