fca62541ca De-duplicate element names in ILIAS crawler
This prevents any conflicts caused by multiple files with the same name.
Conflicts may still arise due to transforms, but that is out of our
control and a user error.

ce1dbda5b4 Overhaul colours
"Crawled" and "Downloaded" are now printed less bright than "Crawling" and
"Downloading" as they're not as important. Explain topics are printed in yellow
to stand out a bit more from the cyan action messages.

afac22c562 Handle abort in exclusive output state correctly
If the event loop is stopped while something holds the exclusive output, the
"log" singleton is now reset so the main thread can print a few more messages
before exiting.

552cd82802 Run async input and password getters in daemon thread
Previously, it ran in the event loop's default executor, which would block until
all its workers were done working.

If Ctrl+C was pressed while input or a password were being read, the
asyncio.run() call in the main thread would be interrupted however, not the
input thread. This meant that multiple key presses (either enter or a second
Ctrl+C) were necessary to stop a running PFERD in some circumstances.

This change instead runs the input functions in daemon threads so they exit as
soon as the main thread exits.

e4f9560655 Only retry on aiohttp errors in ILIAS crawler
This patch removes quite a few retries and now only retries the ilias
element method. Every other HTTP-interacting method (except for the root
requests) is called from there and should be covered.

In the future we also want to retry the root a few times, but that
will be done after the download sink API is adjusted.
