title: Automatically passing html attributes to svelte components
body: <p>Is it not possible to allow svelte components to automatically apply all regular html attributes to the top most element within the component?</p>
  
  <p>Component.html</p>
  
  <pre><code>&lt;div&gt;
    &lt;slot&gt;&lt;/slot&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Application.html</p>
  
  <pre><code>&lt;div&gt;
    &lt;Component class="extend"&gt;
      Some text
    &lt;/Component&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>And have the .extend added to the div inside the Component?</p>
