Only use translations that are >=80% complete
This is a spin-off ticket from legacy/trac#26543 (moved). Antonela says:
I think is good to show just 80% completed languages. If not, the site looks like broken for non-speakers. Let's have emmapeel in this party so we plan an open a call for translators just for bridge.tpo and gettor.tpo :)
After a cursory look, babel can tell us the completion of a translation while compiling it:
$ python setup.py compile_catalog -l uz running compile_catalog 25 of 60 messages (41%) translated in bridgedb/i18n/uz/LC_MESSAGES/bridgedb.po compiling catalog bridgedb/i18n/uz/LC_MESSAGES/bridgedb.po to bridgedb/i18n/uz/LC_MESSAGES/bridgedb.mo
Another thing worth considering: 80% completion is not the same as 80% reviewed as emmapeel explained.
