Last week I spent time on the general problem of pulling translations into plugins:
I automated the pulling in of new translations:
The trick is to pull in new translations (run tx pull --minimum-perc 50 --all in the plugin) before you pull from Transifex (run make -C locale tx-pull in the plugin). Then you extract strings (run rake plugin:gettext[$PLUGIN] in foreman) and build the files (run make -C locale mo-files in the plugin).
