Comment (by vorner):

 Hello

 It seems you forgot to add the `sqlite3_datasrc_messages.mes` to git, both
 distcheck and compilation complain about it.

 I think the `ignore_duplicates` parameter should be documented, also
 noting it'll clear all previous duplicates stored.

 A documentation of MessageInitializer class may need to be updated to note
 when it is being used from dynamically loaded module, it might be needed
 to call the `loadDictionary()`.

 Also, I believe the whole exercise with the dictionaries was done so the
 log messages can be translated and the messages then replaced by newer
 dictionaries. But this kind of breaks it IMO (not that we would be doing
 so, though). It would now look like this:
  * Initialize the english built-in dictionaries.
  * Load translations to override the already loaded messages.
  * Load something from dynamic module. This'll override messages for that
 module that were supplied with the translated module.

 Also, changelog?
