Add a second qrcode of private key for backup purposes #140

Paper wallets could be used as cold storage, so backup the wallets is a reccomended practice. A way to incentivize the user to create a backup is adding into the wallet a second copy of the qrcode on the right. The user could cut it out and store it in another place simply.

why not simply printing the same sheet twice? of course you should keep them in different locations. also you could use the BIP38 feature for encryption and store the resulting PDF, also easy to backup.
