As an archivist or a system administrator I would like an easier way to translate the labels in the staff and public interface

Right now translations for the interface labels are provided by editing a set of yml files individually and there is no way for multiple users to work on them together. I would like a more user-friendly way to translate these. This translation service could exist outside of the ArchivesSpace application, though ideally it would be linked from within ArchivesSpace.
