Display node URI below invoice

[Sjors]

This is useful if the user doesn't have a path to your node yet or if all inbound channels are full. It could be an optional setting.

This could be added to Lightning Charge built-in checkout page, but note that this is only used by Lightning Publisher and nanotip, while the rest of the Lapps self-host (and self-design) their checkout page. Getting this information displayed on the other Lapps is separate and should be tracked with separate issues.

Any UX/designers willing to help with making this information available in the UI for the Lapps, or even with a wider overhaul for the checkout experience? 😀
