MMark -> Pandoc AST

[srid]

See how feasible it is to completely switch over from MMark to Pandoc AST.

• Markdown to be parsed using commonmark-hs (default);
  • in future potentially we could support multiple source formats (including Pandoc's native markdown parser, org-mode, reST, etc.)
• Use HsYaml to manually parse the Yaml blocks (unless Implement yaml_metadata_block extension jgm/commonmark-hs#17 gets implemented by someone)
  • Make sure it works with GHCJS
• Profile and identify performance bottlenecks
• Make fontawesome icons work (Pandoc AST cannot represent <i> with custom classes).
• Modify the rest of neuron to switch over to the new parser
• Use necessary commonmark extensions (eg: math)
• Port/add unit tests
• Documentation updates

Finally,

• Pandoc HTML Writer -> Reflex DOM #172 Replace pandoc's writer with reflex-dom-pandoc (to be GHCJS friendly)
  • Footnote links are broken (pandoc writer)

If successful, this will resolve #137.

HsYAML is rather slow. haskell-hvr/HsYAML#40
