This reverts commit 14134d61fb4b1bbf4ce80bb9b3ed849908bf9344, reversing
changes made to 6a876ef8ec3e2aeb3d15df0dfb0e07677e49ff03.
This causes translation failures, this should be reintroduced when the
CI check passes.
I don't see any actual changes here, just reordering. It's using the Nix
environment so I'm not sure why this happened but it seemed to stem from
the Norwegian work originally. Fixing it back.
This is my third (!) attempt at implementing localization support.
By leveraging GTK builder to do most of the `gettext` calls, I
can avoid the whole mess about missing symbols on non-glibc platforms.
Added some documentation too for contributors and translators,
just for good measure.
