handle title and desc element with SVG tag

[jimblue]

Actually there is no solution to add a <title> and a <desc> to a svg with the {{ svg }} tag while thoses elements are very important for a11y.

So it could be nice if the following markup:

{{ svg src="mybrandlogo" class="brand-logo" title="My Brand logo" desc="Uppercase text reading My Brand"

would output:

<svg xmlns="http://www.w3.org/2000/svg" aria-labelledby="title desc" viewBox="0 0 100 20">
  <title id="title">My Brand</title>
  <desc id="desc">Uppercase text reading My Brand</desc>
  <path d="..................." />
</svg>
