Donation banner translations

Transifex has translated the donation banner to many languages. If we want to include the donation banner in some of these locales, we will need to explicitly activate those locales in the donation banner code. And we will need to adjust the text size and/or layout to accommodate the variation in text length between languages. Which languages should we include?

Finally, we will need to import the latest translations from Transifex before building TBB.
