Subject: improve generate.py

* Add ability to choose subdir name format.
* Add day (D) as a variable to use.
* Add ability to use other exif date tags, and filename, to determine
the date to use. Timestamp is a last-resort option only!
* Change output of the cli equivalent actions to stdout (from stderr).
