/**
 * Reusable XSS-safe html-builder DSL.
 * Taken from Roberts userscripts so we can avoid insecure innerHtml nonsense.
 *
 * Example:
 *  $builder('div')
 *      .id('foo')
 *      .className('a b c')
 *      .onBuildText('<b>Test</b>')
 *      .build()
 *
 * Result:
 *  ```
 *  <div id="foo" class="a b c">
 *      &lt;b&gt;Test&lt;/b&gt;
 *  </div>;
 *  ```
