* apparently, the previous config-based approach stopped working

* add alt text to images
* add rel="noopener" attribute to links
* add caption to tables

* also, remove unused utility function

* use blueprint entrypoint instead of initializing it in the extension
* move finalize_app code into a new separate module

* so that we can react in case the original author doesn't have access
  to their account anymore
* and also so that we can measure the amount of spam

* because the previously configured image didn't actually exist anymore

* if a user has permission to preview a draft but not to edit it, we now
  redirect them to the preview page instead of rendering the "permission
  denied" error

* that eliminates the necessity to open up colab just to copy the text
  again
* also, it automatically pre-fills the proper names in the template

* make it the same colour as the control bar

* this usually happens when the search engine isn't ready yet after a
  redeployment

* provide a 160px wide version of the FAIRsharing logo
* it's much less data to transfer than the 1600px wide logo
* this is basically the maximum size used for any screen size anyway

* it's a bit smaller than the WebP and scales better

* because it's not highly relevant information, and it's not immediately
  clear what it is

* their functionality can now be emulated with banners

* we disabled `community-submission` requests in Invenio-Config-TUW
* selecting a community through this field would result in some HTTP
  calls returning 400 code responses with vague error messages (which
  are currently ignored in the deposit form JS as well)
* so instead we just hide the field in the UI altogether (the API is
  guarded by the above mentioned settings)
* the CSS selector is pretty bad, but I couldn't identify a much better
  one...
