Add a "Keyword Token" for folder-naming on Export

I do a lot of travel photography. I use keywords to specify the place names of images. When I export images, I'd like them to be saved into folders depending on this place name keyword.

I understand that there might be an issue as to which keyword to use if there is a keyword hierarchy. For example:

• Places

  • Portugal

    • Porto

I would be happy just to be able to treat the full keyword hierarchy as a folder hierarchy.
