Canton Becker 4e5b4133ef Look & feel changes, added PGP signature 
Made buttons more button-like, clarified instructions, and added a PGP
signature for the generator (along with instructions on how to validate
the .sig file.)

<h1><span id="instructions0">Welcome! Let's print out a beautiful and secure wallet for your bitcoins.</span></h1>
<span id="instructions1"><em>Here's an overview of what will happen, step by step.</em></span>
<br /><br />
<span id="instructions3"><b>Step 1: Calibrate Printer</b><br />
Before printing out a wallet you'll need to "calibrate" your printer for <b>zoom</b> and <b>horizontal shift</b> to accommodate your particular browser / printer combination. Without proper callibration, your wallet will end up the wrong size or with a misaligned reverse side.</span>
<br /><br />
<span id="instructions4"><b>Step 2: Print Front</b><br />
Next we'll print out the front side of your wallet. A public address and private key will automatically be generated.</span>
<br /><br />
<span id="instructions5"><b>Step 3: Print Back</b><br />
Then you will put the same page back in your printer (but upside down) to print out the back side of your wallet. This isn't just for good looks: the back side design includes additional tamper-resistant safeguards.</span>
<br /><br />
<span id="instructions6"><b>Step 4: Cut, Fold, Seal &amp; Fund</b><br />
Find your scissors! Time to cut out your wallet, fold it, and seal it with opaque (light-blocking) tape&mdash;or better yet <a href="https://bitcoinpaperwallet.com/#purchase" target="_blank">tamper-evident holographic tape</a>.) Now you're ready to transfer bitcoins from your online holdings to your new wallet.</span>
