Hugo 0.22.1

Hugo 0.22.1 fixes a couple of issues reported after the 0.22 release Monday. Most importantly a fix for detecting regular subfolders below the root-sections.

Also, we forgot to adapt the permalink settings with support for nested sections, which made that feature less useful than it could be.

With this release you can configure permalinks with sections like this:

First level only:

[permalinks]
blog = ":section/:title"

Nested (all levels):

[permalinks]
blog = ":sections/:title"
