Translation template mixes user facing and devel facing strings

[Alejandro J. Cura]

The names of the departments (and highlights, and other strings visible on end users devices) are all mixed with the very many strings of devportal which are only visible to devels submitting apps.

That means that it's a lot of strings to translate, and that many languages are missing those: https://translations.launchpad.net/software-center-agent/trunk/+pots/devportal

We have ~30 departments that most users will see, and over 1000 strings to translate that only devels will see.
It's not trivial for translators to find which ones are departments, and prioritize those.
