translations: use the right Qt translations (part 2)

Browse source 
It turns out that contrary to what the documentation states, a few languages
are still only using the 'qt' translation. But those exist for all languages,
so we need to first search for the 'qtbase' translations, and only if that
fails do we try to load the 'qt' translations.

And even that will fail for languages in which Qt simply isn't localized (like
Dutch).

To make the code more readable, the check for 'US English' was moved earlier as
there is no point to look for a Qt translation for that (simply doesn't exist).
