Merge changes from forks

[WofWca]

Describe the problem

Believe it or not, I looked through all the forks and collected some with considerable changes that have not been merged in this repo (update: should have tried something like this https://github.com/mvoggu/forksAhead). I, however, have not thoroughly inspected each one on what can be merged.
I only looked at those whose default branch has diverged from this repo's, so some I might have overlooked.

Here's the list:

• https://github.com/vendasta/weblate - added a lot of deployment files, but there are also source-code changes, like the addition of namespace languages (?). Not sure how much of it can be merged.
• main...dmitmel:stable-crosscode - autocompletion, API endpoints, some fixes, settings changes
• https://github.com/qinthq/weblate - added UWAI (?) addon.
• main...chervol:master - some minor changes, idk
• main...alvinchen977:main - fuzzy date parsing for search.py.
• https://github.com/CivicDataLab/Anuvad - heavy customization, but no valuable source code changes.
• https://github.com/ValdasRK/weblate - one commit ValdasRK@b543d88

Additional context

Inspired by this discussion. I've also made a copy of some of these in my fork, just in case.
