imprv: Styling: Introduce URI scheme whitelisting
Fixes #11266 (closed)
The IANA data fetching script might need more automation, currently it has to be run manually as scripts/get_iana_data.py > gajim/common/iana.py
.
Btw, it already fetches the list of top-level domains, for the not-yet-written scheme-less link search based on known domains (like dev.gajim.org/gajim/gajim
).
