Updated translation of the new Spanish terms for v3.9.1

Updated translation of the new Spanish terms for v3.9.1 and some coherence changes.

The issue discussed previously with a couple of translated terms that are shown untranslated seems to persist in the current nightly build, but hopefully won't affect the v3.9.1 release this time either. 😄

Fantastic @lulol, thank you very much. 😀

[justinclift]

Oh, I forgot to ask... do you want me to take screenshots, so you can double check?

[lulol]

OK, can't hurt to check at least if the terms shown untranslated in the nightly build are translated in the release.

[justinclift]

Cool, I'll get it them done soon. Updating some other things first. 😄

[justinclift]

Screenshots: 😄

Made 4 minor corrections to the current terms and generated a new pull request, that if there are no more changes seems all good for the release.

[justinclift]

Thanks @lulol, just merged it. 😄

No further string changes will be happening for 3.9.1, which I'll start building packages for in a few hours, and we'll probably release tonight.

Cool!

If for the master there are any changes, can also take a look at them. 😄

[justinclift]

Thanks. The master branch isn't important yet. When it starts to be important though, I'll email you again. 😄
