Main changes

Add support for LNURL-pay

LNURL-pay is an offband protocol using http requests to get invoices from a compliant node. It supports comments, min/max amounts, metadata (including images) and callback messages from the recipient (including encrypted messages that can only be read once the payment is successful, using the preimage).

This change does not mean that Phoenix offers static invoices, but that it can now pay them.
