Translation wizard must allow passing additional data
Currently, the translation wizard in the page module only passes the colPos to the AJAX translation handler. For structures as defined by e.g. Gridelements or Flux, this is not enough, as the location inside the structure must be known to fetch elements for translating.
Also the additional data must be taken into account by the AJAX translation handler. This could be done either by changing the core translation handler to handle additional data (or call processors in a chain) or by overriding the handler with a custom Xclass in extensions like Flux or Gridelements.
