Adding JSON Feed Support

For no particular reason, I decided to try to add support for JSON Feed for my blog here.

I write everything here in org-mode files & publish it using an Emacs script, based on Ambrevar’s setup. That uses feed-builder.el to generate the XML for RSS, which is pretty simple, so I took a shot at implementing the equivalent for JSON Feed.

That code can be found here. I may publish it later, or perhaps see if Ambrevar would accept a change to make his library able to generate JSON as well as atom or RSS.

I also took the opportunity to make little SVG icons for the RSS & JSON feed links, just for fun.
