CanIUse: Create aliases instead of duplicate articles, use <ul> instead of <br>, and more

[moollaza]

Issues to be Fixed

1. Currently we create an array of titles and loop over that creating individual articles
   • We should instead create redirect entries from within the parser
   • OR, build a separate redirects.txt file that will be used internally to generate all the redirects
2. After the initial paragraph of text, we have a list of supported browsers that are separated with <br> -- we should instead build an unordered list using <ul> and <li>
3. The Notes: subtitle should be wrapped in <span class="prog__sub"> instead of <p>, the bolding should be removed
4. The list of notes should be a <ul> as well, instead of multiple paragraphs

The final markup should look like this:

<section class="prog__container">
    <p>Method of defining a linear or radial color gradient as a CSS image.</p>
    <ul>
        <li>IE 10+ ✓</li>
        <li>Firefox 16+ ✓</li>
        <li>Chrome 26+ ✓</li>
        <li>Safari 6.1+ ✓</li>
        <li>iOS Safari 7.0-7.1+ ✓</li>
        <li>Android Browser 4.4.3-4.4.4+ ✓</li>
    </ul>
    <span class="prog__sub">Notes:</span>
    <ul>
        <li>Syntax used by browsers with prefixed support may be incompatible with that for proper support.</li>
        <li>Support can be somewhat emulated in older IE versions using the non-standard "gradient" filter.</li>
        <li>Firefox 10+, Opera 11.6+, Chrome 26+ and IE10+ also support the new "to (side)" syntax.</li>
    </ul>
</section>
