Code review comment for lp://staging/~adiroiban/launchpad/bug-564852

I am not using a set, since Language.translators is already sorted by karma (done in a single SQL query).
Using a set and then resorting it at the end will require a new SQL query for each person.

KarmaCache can not be updated from the „browser” layer and we need a unit test for services.worlddata.model.language.Language.translators running in LaunchpadZopelessLayer.

I have extended the current Language.translators karma text code to check that translators for a language are sorted according to their karma value.

Here is the latest diff:
