[Feature Request] Include a hidden <img> tag inside <v-img>

What problem does this feature solve?

The current implementation of v-img renders the image inside a background-image. While this is the intended behaviour to achieve the correct sizings, the lack of a real sibling img tag prevents tools like Safari Web Reader, which are very important for accessibility, to identify such images.

What is your proposed solution?

The proposal is to render a hidden img tag as a sibling of div.v-image__image.

The Polymer team has this feature at their element iron-image and works like a charm. Their implementation is available at: https://github.com/PolymerElements/iron-image/blob/master/iron-image.js

Because you can’t have it with an empty aria-label, so it defaults to the equivalent of <img alt="">

If you supply alt text then role="img" will be used along with aria-label.
