Updating my env, I found some untranslated strings in Brazilian Portuguese.
Taking a look into translate.jitsi.org, I saw that all strings are
translated. So, I got this untranslated strings and tried to find then into
current strings, without success.
So, I took some print screens and added in my issue (#1157) to update pt-BR
translation. Now, I understand that the best is to revise the translatable
string list into Pootle for update the translations.
