 * Overview: Projects could have more than one template for the same series. In those cases, maintainers want to request to download all translations in a single step.
 * Goal/Deliverables: Give an option from Launchpad UI to request a full export so you get a tarball with all templates and translations available for that productseries.
 * Full spec: none
 * Depends on: n/a

{{{
We will know we have finished when anyone is able to download all templates and translations for a productseries in a single step from the UI.}}}
