Allowing to wrap <img> in <figure>

[alexJunger]

I found it useful to allow wrapping the img in a figure tag and add a figcaption, based on the description you enter in the popup - makes a little better use of it than just putting it in the alt attribute imo. In the init call, add uploadimage_figure: true to create this structure:

<figure class='figure'>
  <img src='..' alt='whatever'>
  <figcaption class='figcaption'>whatever</figcaption>
</figure>

You can also pass other classes with uploadimage_figure_class and uploadimage_figcaption_class
