[Tails-l10n] Call for translation: 1.5.1 release notes and s…

Hi, translation team!

I've just prepared a Tails 1.5.1 emergency release. Please translate the
following PO files in the 'stable' branch (or, if the release has
already happened, in the 'master' branch):

* wiki/src/news/version_1.5.1.*.po
* wiki/src/security/Numerous_security_holes_in_1.5.*.po

It's very little work do to this time. :)

Cheers!
