Need for derivative translations support
We need a way to group translation of the same language and only have small specification per country\/flavour\. \ I propose that trytond tries first to pick a translation including country if there are none or it is empty then it tries to pick the translation from language only code\. \ On Pootle\, the translators when translating for a country\, will have to configure Pootle to show the language translation and so he will leave it empty if it is the same\. \ http\:\/\/docs\.translatehouse\.org\/projects\/pootle\/en\/stable\-2\.7\.2\/features\/alternative\_source\_language\.html \ Also I think a cleaning will be needed for the current duplicate languages\.
