Display Zigbee Network Address in Hexadecimal in the Openhab properties.

[FranzSchi]

As a developer/power user, I want to see the Zigbee network address in hex (e.g., 0xFA0C) in the device details, So that I can quickly search for and identify the device within system logs without performing manual decimal-to-hex conversions.

This field is numeric and as far as I know there is no way to show it in hex short of changing to a string. I think it's pretty easy to convert between hex and decimal :)
