* Hebrew
* Japanese
* Korean
* Dutch
* Portuguese (Brazil)

With #300 being a feature scheduled for 0.2.0, we should make sure to
inlcude those strings before the string freeze on Feb 15.

Once this is merged we should add a comment on Transifex to give
translators some context.

With #289 being a feature scheduled for 0.2.0, we should make sure to
inlcude those strings before the string freeze on Feb 15.

All those strings are equal in Briar Android, but still it makes sense
to include them to allow translators to review and test the
translations.

They are currently at 87%, so they should be safe to get included in 0.2.0.

Including those strings now allows our translators to test the
translations in the app with the nightly builds.
