Translations pass my minimal QA checks (all messages translated, checkPoFile() passes, marked as UTF-8) 🎉

cc @Rdatatable/spanish members who could maybe do a pass as reviewers of translations per se?

I'll go ahead and merge, other translators feel free to file a follow-up with copy-edits to the translations if you see fit!
