[Tails-l10n] Listing Transifex translators

Hi,

there's now wiki/src/contribute/l10n_tricks/transifex_translators.sh
in Git, that (provided you've used e.g. ./import-translations to have
an up-to-date tor-translations clone in tmp/) lists people who did
translation work on Transifex. Credits go to Ague for the initial
version of this script.

Should be useful for the "if you're a Git-using team, you should get in
touch regularly with the translators on Transifex so that they don't
waste their time without anyone telling them" duty.

Cheers,
