<p>We need to support listing paid site templates in the installer. I discussed with @mherchel and @andyg5000 (Dripyard) and we decided we should:</p>

<li>Allow site templates to show a price, and a "more info" link</li>
<li>They should also be able to supply an off-site purchase URL.</li>
<li>When a paid site template (anything with a purchase URL) is clicked, the site template form's "Next" button changes to "Buy Now", and clicking it will open in a new window.</li>
</ul>
