Hugo: Feature Request: Add default permalink format configuration setting

[theory]

Following up on this Discourse topic, I'd like to request a method, perhaps a global config setting, to set the default permalink format. That is, if there is no entry for a section in the [permalinks] config, it would fall back on this new setting. Currently, it appears to be hard-coded to /:slug/.

I think this issue is relevant and valuable because, without the requested feature, one must create a separate permalinks entry for each section of the site. If one adds a new section and forgets, one might end up with a URL one doesn't want. It's nice to have the ability to set the default rather than rely on a hard-coded default.

I was just about to create a new issue with this very same feature enhancement request, but managed to find an existing one first. I have the same situation, we'll be using the same URL format for all posts on the site, regardless of section. It doesn't make sense to redundantly specify the same configuration directive for every section, and take the risk of publishing incorrectly formatted URLs in case you'd forget to reconfigure things when you add a new section for your posts, as these may end up used by others.
