Advanced: ReserveProof: Add support for reserve proof
This change adds the ability to prove and check a reserve proof to this existing "Prove/check" advanced menu. If the amount line has a valid amount less than that of the current account index this input will drive the logic for generating a reserve proof. Checking a reserve proof is accomplished by validating the address and verifying that signature.indexOf("ReserveProofV") === 0. The result displays the total and spent amount of the proof.
