2020-12-05 Gemini clean URLs

I'm a fan of "clean" URLs, i. e. those without a file suffix/extension, like ".gmi".

As for the gemlog, I first thought that a directory for each day is too much of a structure and I'll save the Gemini content in files without extension.

Turns out the used Gemini server does not serve the content as Gemini that way.

So let's script the mkdir part a bit.

Also, we might want some meaningful pieces of information coded in the URL, hmm …
