Pretty URLs in Neuron

Just pushed a change that enables pretty URLs in neuron generated sites. This already works in GitHub Pages (/foo returns /foo.html). Neuron had to be changed to make generated HTML link to /foo instead of /foo.html. This behaviour is controlled by:

neuron gen --pretty-urls

Which is also what neuron-template does by default.

Demo:

• This website
• https://neuron.zettel.page/
• https://alien-psychology.zettel.page/
• https://zk.zettel.page/

Other changes

• Default slug is now minimally transformed: especially with --pretty-urls, it is useful to allow the user to reuse zettel title ID for url (except for replacing whitespace for legibility).
  • One can always explicitly specify a slug in the zettel YAML, as https://neuron.zettel.page/ does for virtully all of its zettels.
• Ignore zettels without date in “timeline” queries.
