This changes gomarkdown parser behavior to allow code blocks, lists, etc
to come after other blocks (like paragraphs) and get processed as
independent blocks without a separate newline (putting gomarkdown in
charge to decide whether a new block is started).
This is a breaking change as this affects how some existing Markdown
source might get rendered. Nonetheless, this is probably the expected
default by most users. This has no configurable switch yet.
See #14.
gmnhg is the new program that generates a Gemini site from Hugo site
content. It reads its input from content/, static/, and layouts/gmnhg/.
Its output by default goes to output/.
More doc is available in the program doc header.
This also introduces a simple program, md2gmn, that is meant for testing
the renderer on Markdown files. Nonetheless, it can be used as
a standalone tool as well.
