stash some work I did some time ago on earley hacking.
Merge branch 'blog.pnkfx.org' of github.com:pnkfelix/pnkfx-blog into blog.pnkfx.org
The version of Jekyll on my Mozilla laptop did not like the embedded
unicode forms for the suits  :(.

So I put in the html escaped entities instead, as a quick workaround while
I look into my atom feed issues.
Fixed url (whre did that come from?) after Jack pointed out my atom feed was borked.
