Allow config file to be specified

Currently via environment variable, but for now that's fine as the
only use that I can forsee is for testing, where the plumbing is more
important than the interface.

Add tags listing

Reify taxonomies into just tags.

I'm probably not going to need anything else, and this makes it a lot clearer

It was broken in the upgrade.  Not sure how previous tests missed it.

Works with more than just arrays.  Iterators in particular are useful

fix(responders): replace <main> from layout

refactor: move markdown rendering to domain

The input and output formats (md -> html) are specific to the domain
of blogging, not really a presentation concern.

than per-request
