encointer signer device

[brenzi]

similar to parity signer, the encointer app could be used to sign extrinsics (or arbitrary payloads?) which were generated by a web service / browser extension

Story

1. Business owner wants to update business metadata. This may be more convenient to do on a PC than on a mobile device. bazaar-web could offer an edit function that will take care of publishing content to IPFS. To migrate the entry, bazaar-web will create an extrinsic (or just a call?) with the new IPFS cids and show the user a QR code
2. user scans QR code. App decodes and health-cheks the extrinsic (do not allow arbitrary extrinsics like parity signer)
3. app signs and submits the extrinsic
