Add support for authoring gemtext posts

Updating the build script to allow for posts to be .gmi files in
addition .html files. I added a submodule to gmi2html so we can
convert these on the fly and they'll write themselves to the build
directory as the desired filename which then get hoisted into the www
folder upon post creation - as normal!

This should help with authoring more simple text posts that don't
require complex markup like music stuff! This did require updating
gmi2html to have more support for quote attribution however. So I
should be mindful in the future of how that renders!
