Extension blank_before_header not supported for gfm

[cdmerritt]

All of the images are saved, but no MD files are saved.

I see this in the output:

Parsing ... somefile.html
Making Markdown ... somefile.md
The extension blank_before_header is not supported for gfm

@cdmerritt Where did you change that? I made your suggested change in App.coffee, but now I get Unknown extension: markdown_github.

@crfroehlich, yes, App.coffee.

  @outputTypesAdd = [
    'markdown_github' # use GitHub markdown variant
    'blank_before_header' # insert blank line before header
#    'mmd_link_attributes' # use MD syntax for images and links instead of HTML
#    'link_attributes' # use MD syntax for images and links instead of HTML
  ]
