Add an event mapping that enable to display existing translation by default
In some application, the WebLab document that can be processed are translated because they are in a language not read by the users. It would be interesting that the availableTranslation (if any) were displayed by default when arriving on the document viewer page. The idea is to add a new EventMapping and to let the applications configure or not to use this event mapping instead of the selectNotLoaded.
If the received document has no available translation, then the original document should be displayed!
