Also allow disabling author export.
This commit might be a big behavior change for some as now the author
name is auto-exported to the post front matter.
To disable that, simply put "#+AUTHOR:" or "#+OPTIONS: author:nil" at
the top of your Org file.
With this commit, ox-hugo now supports one more implicit ox.el
feature.
Part of solution to https://github.com/kaushalmodi/ox-hugo/issues/106
Fixes#89
- Restore the default Org behavior of `#+TAGS`. Now that keyword (and
the `EXPORT_TAGS` property) is **not** used by `ox-hugo`.
- File-based exports must now use `#+HUGO_TAGS` to set the post tags.
- Subtree-based exports can use the `EXPORT_HUGO_TAGS` property to
override Org-style tags on the same headline (and the ones inherited
from Org-style tags from any of the parent subtrees and
`#+FILETAGS`).
- Note that for subtree-based exports, `#+FILETAGS` can be used to
set tags globally in the file. Earlier `#+TAGS` was used for
that purpose.
- Subtree-based exports can use the `EXPORT_HUGO_CATEGORIES` property
to override Org-style categories (tags with "@" prefix) on the same
headline (and the ones inherited from Org-style categories from any
of the parent subtrees and `#+FILETAGS`).
- Note that for subtree-based exports, `#+FILETAGS` can be used to
set categories (tags with "@") globally in the file.
