Or we could get ckan to provide the list of languages it is using (via
config options, ec-portals auto-detect languages etc)

That is useful and seems quite painless once it's setup, my only worry
would be about things like datetimes etc but there is some logic around
this but it looks like it is fixed key names - not sure how we deal with
dates in custom fields but that's not an issue for now - maybe regexs would
be good enough.

What I really want is to be able to translate field names for custom fields
and things like that.  As we are not wanting the keys of the dicts
translating this will have to be done separately  some sort of ckan _
helper function I'd imagine.  But could definitely share the basic
implementation.

Maybe @kindly has some input

Anyway this is something that I'm still pondering so any implementation
won't start for a few weeks
