i18n our errors

[stevan]

We discussed this, the errors put into the document can either be a string, or then can be a HASH ref with a single key "code" which contains a string which can be fed into an i18n mechanism (Locale::Maketext, etc) and properly i18n these errors using some kind of plugin.

Or, we could do it totally different.

while this is easy to control in PONAPI, what about the messages raised by the repository through exceptions? this can lead to a mixture of languages in different responses for the same client/server communication session.
