add i18n scripts and pot file

[circlecube]

Proposed changes

Adds i18n scripts and the pot file. We'll need add the translations before this is properly i18n-ed, but the strings are all loaded in PHP and added to the newfoldDeactivation script and js loads the strings from there, so we shouldn't need json translations for now.
