Feature Request: Add blog indices to project-level URLs

[rossbar]

Currently the urls for the blog posts look something like:

https://blog.scientific-python.org/posts/scipy/internships/smit/

It would be nice if the project directory (i.e. posts/scipy/ in the above) contained an index/listing of project-specific blog-posts.

I think this is supposed to be the tag functionality no? On StackOverflow for instance, you can associate a description to tags. That would more or less do it I think.

We already have: https://blog.scientific-python.org/tags/scipy/

There are a ton of other features we could add, but someone need to implement them. PRs welcome.

[jarrodmillman]

You could add an index file with a link to the tags page.

We may also be able to use URL redirects.

I show how to implement this in #153

The PR does not add atom.xml files for subdirectories, but it shouldn't be hard to enable.
It does raise the question of whether we expect users to filter predominantly by tags or directories (I think so far it's been clear that we fully rely on tags, which have listing pages + RSS feeds generated).
