I had overridden Hugo's OpenGraph template to improve it, but those
changes have been upstreamed in Hugo 0.19. We can use theirs now.

I had overridden it in the theme to improve the metadata generated
by it. Hugo has accepted the changes upstream so we can use theirs
now.

Hugo 0.18 introduced the imageConfig function which allows you to
access the height and width of images, which makes bots consuming
the structured data happy.
.Site.LastChange is the date of the last modification on the entire
site, not necessarily on the node we're currently showing, such as
a taxonomy list.
I'm not sure if it really matters to bots who will parse this (it's
much more important on content pages of course), but using .Date on
nodes like the homepage and taxonomy terms pages will set the date
to be that of the latest post in that range—to me this does indeed
seem to be "time when the object was last updated"[0].

Hugo's current handling of dates in the opengraph partial needs
nome work to be more correct—for example: the usage of published
and updated times. This comes verbatim from the Hugo source tree.

Allowing users to select specific icons they want to show makes the
configuration and logic a bit tricky. A user brought up the case of
disabling sharing icons on certain pages/posts, and it was actaully
not possible without adding lots of extra logic, not to mention the
pain of having to test all possible configurations.
Instead, it is much simpler to just allow sharing icons to be either
on or off as desired in the site config or page/post frontmatter:
sharingicons = false
Otherwise, sharing icons default to being enabled, as this is most
in line with what would be expected on a "blog".
This replaces the metadata that Hugo's own schema.html template had
been providing, but does so in JSON-LD notation rather than via the
use of <meta> tags (this is Google's currently recommended form of
specifying this markup). There are a few exceptions where I did not
follow the conventions used in Hugo's template, for example the use
of up to six images from a post's frontmatter, because Google's tool
only recognizes one image, as well as different logic for a post's
publish and modified dates (using enableGitInfo = true).
Using this new markup, Google's Structured Data Testing Tool is now
able to understand site metadata much better (before it was reading
none).
The implementation here is a mix of the elements and types from the
official Schema.org types—for example, Blog and BlogPosting—as well
as from Google's search documentation. Note that Google's docs are
geared towards AMP, where some metadata is required, while for non-
AMP pages the metadata is just recommended.
We will have to re-evaluate this in the future, for example to add
height and width information to image metadata.

As of Hugo 0.18 .Site.Pages now returns all pages, including pages,
home, taxonomies, etc, and you are expected to filter them by their
"kind". There is a new variable .Site.RegularPages which returns a
range of "regular" pages like in pre-0.18 Hugo.
In this instance we are limiting the range to pages with the type
"post", so our current behavior works, but I'd rather be consistent
with other ranges we're using, like on the homepage and taxonomy
list pages.

If the user's config doesn't have [params.sidebar] defined they get
errors when trying to build the site. It's better if we just check
that this config block is defined before trying to use it, and then
add something to the docs telling people that the site looks really
bad without this defined.
Bring the Disqus comments inside the <article> tag. The article has
a sizeable bottom margin seprating it from the blog footer, and if
Disqus comments are active they appear after this margin, and this
looks ugly.
Semantically, I think the comments should actually be inside the
article tag anyways (since they are directly related), as well as
further wrapped in article tags, but we don't control the code that
Disqus injects so we'll have to make do with this.

Prepending the site's URL to relative links was a hack but at the
time I couldn't understand why href="#" didn't take us to the top
of the page. It turns out that this was because of the <base> tag
that I have now removed.
It was screwing up relative links like the ones in footnotes. I'm
not sure why I added it in the first place, actually, as the docs
specifically say "specifies the base URL to use for all relative
URLs contained within a document".

* Add Vim modeline comments to all relevent template files.
* Add Vim modeline comments to a few other files.
* Move modeline comments inside the template definitions in list and single.
For some odd reason, putting them outside breaks the page generation.
* Use template comments for modeline comments in templates.
* Fix form 2 modelines.
Set the cookie_consent_info_url parameter in your site's config to
display a message about cookie usage to your users. See the config
in `exampleSite/config.toml` for more info.
We are explicitly using the site's RSS feed, but after reading the
Hugo RSS docs I think it's better if we use the contextual version
of the RSSlink. This will make the RSS plumbing show a feed for the
current category, tag, section, etc. The example code also adds a
bit of markup to help browsers find the content more easily.
See: https://gohugo.io/templates/rss/
Instead of writing my own logic for metadata and Twitter cards, I
should be using Hugo's own. This makes my theme code cleaner, but
means I have to adjust some of the configuration conventions that
I have been using. An added bonus is that my theme will work with
more sites now, as long as they are using Hugo's config conventions.
Sites only need to add their Google Analytics tracking ID to their
config:
googleAnalytics = "UA-123-45"
This uses the async version of the Google Analytics code.
