merges in transifex
we still need to merge some more language codes:
- hr and hr_HR: some mmiscommunication, translators need to agree on the merge and if they choose hr_HR we need to remap.
- es and es_ES: es_ES is dead, the real translation is at es in Transifex, but we map it to es-ES in Torbutton branches
- pt and pt_PT should be merged?
Other cases still to define, maybe in other ticket:
- nl-BE has no locale in Mozilla, so we should not make translators translate TorBrowser to it.
- There is Mozilla locale for Swahili now!
