Implement renderer test suite
This implements a Markdown / Gemtext suite, testing the entire renderer
at complex Markdown documents, containing the entirety of current
Markdown features accessible with gmnhg. The test suite can be expanded
by adding a pair of .md/.gmi files.

Minor bug fixes in JSON/Org metadata parsing where bugs were detected
with the test suite are also included in this patch.

Fixes #13.
