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.
