Ensure that the configuration import is run before the database updates,
so that any new fields are created that are needed within the update
steps such as `field_type` on the talk node type.
Add the ability to add links to external blog posts within my blog feed.
This is done based on a new `field_external_link` field that allows for
adding the external link URL and the domain name as the title.
The node links are then overridden to use the external link if there is
one, so the node title and 'read more' links are changed to use the
external link.
Currently, automated tweets are not generated for external posts.
Fixes#182
Check if a post has previously been sent to social media, by checking
the value of a `field_sent_to_social_media` field.
This field is hidden on the node add/edit forms, and populated when a
post is sent to social media. Once this happens, it will not be sent to
social media again.
This change also populates the field for all existing posts, so that
they won't be re-sent to social media either.
Improve the accessibility for the nav toggle button by adding a border
around the button when it is focussed on.
I've added a custom Tailwind CSS variant to do this using a custom
`focus-visible` variant in tailwind.config.js, and using the
https://www.npmjs.com/package/focus-visible polyfill.
