LP1691269: Webstaff Copy Editor Templates

This branch will translate and transfer your XUL client templates
the first time you load the web client copy editor. From that point
on the two diverge with no further connection to each other.

This branch also allows your copy templates to travel with you
between browsers, machines, and so on, while still allowing users
that share a browser but not usernames to have their own templates.
