Figure extensions for Wagtail markdown.

This is a simple extension to look up unresolved reference style image links in a markdown document in a modelcluster and render them as figures.

There are currently three pieces here.

• The markdown extension replaces unresolved image links ![My alt text][my_handle] with the django-esque tag {% figure my_handle "My alt text" %}.

• The filter link_figures replaces the above tag with the expansion of the user supplied template figure.html, using as context

  • smart_image: the image with handle my_handle in the images of the filter's argument.
  • alt = "My alt text"

  The package also provides another filter, link_md, that just appends links to the pages images to produce a self-contained standard markdown document.

• An abstract parent model, ImagesPage for pages that have a set of images with handles to be used by the above process. This automatically produces the image container model with ParentalKey pointing at the page model and the method Images in the page model. The image model name is read from the WAGTAILIMAGES_IMAGE_MODEL setting.

This code is slowly being factored out of my web site. In particular, don't expect it to be good or even usable yet.
