* with transparent background
* and 1000x1000 px resolution

* Remove 'FAIR Data Austria' logo as it's not relevant anymore
* Revert to the layout for 4 logos
* Change dimensions of 'InvenioRDM' and 'FAIRSharing' logos to fit better in the footer according to the max thresholds

* this behavior can be controlled via a configuration flag
* it's disabled per default because it could be used to spam the inbox
  of arbitrary email addresses

* with a default of 5 attempts per hour
* this should be enough for legitimate requests, even with failed
  attempts (i.e. captcha mismatches) but still prevent spam floods
* also, hide the contact form for users when viewing their own records'
  landing pages

* use <pre> rather than <blockquote>, because the latter doesn't
  preserve newlines, etc. which may be unexpected given the textarea
  input

* Add FAIRsharing logo and adjust footer CSS grid

* escape the user-supplied values in the HTML email
* also, remove the whitespaces introduced by the license comments on top

* add *.jinja templates (for the email templates) to the MANIFEST.in

* this is possible since we configured sending of emails from the
  backend
* it replaces the current implementation of "contact uploader" that
  worked via "mailto" links, which was suboptimal because it exposes
  email addresses to the public
* it is also optionally protected via a captcha as a simple spam
  prevention mechanism that also prevents accidental resubmission of the
  form on refresh

* chase frontend build project changes in Invenio-Assets
* also many thanks to ULB Münster for the help here!

* because the changes have been merged upstream in Invenio-Previewer
  v1.3.9

* create a config item THEME_TUW_FRONTPAGE_INFO for the content
* add a block in the frontpage.html
* apply styling

* this has no business being hard-coded

* The previously defined `grid` class (targeted for the footer) had the same name as the one from semantic-ui-less. This caused some styling to be inherited by other elements throughout the page when it shouldn't.

* Footer now uses grid instead of flex
* Layout and alignment improved throughout different screen sizes

* Further improve the text, change header icon

* Rework the text

* Improve text & add icons

* Previously a star wildcard was applied in the css, eliminating margins on all header elements when it shouldn't (e.g. Log in text and icon spacing). We use specific class margins in the html template instead.

Add SLS document link (Only in German for now)

* this caused issues on the draft preview page
* when a draft didn't have a published record with the same ID, the new
  filters couldn't find any results and an exception would be raised
* this exception was caught by the registered error handlers and masked
  as 404
