Allow to re-play form submissions

In short: If we would also store the form_id and form_values for each journal record, Journal module was probably able to re-play a site setup, for example to create a similar Drupal site.

With some more export/import logic (i.e. checkboxes to select certain journal entries), Journal could probably also provide kind of snippets (sub-sets of all Journal entries) to apply a particular site configuration.
