Description
This change-set add the definition of a uuid field at the revision_history type.This new field will be used to register the UUID of the change responsible for a specific edit.

* faster recreation of the history of a single file walking backward in time from edit.uuid to edit_origin.uuid;
* time safe behaviour of the history tool.
This change-set only add the definition of the field, it's not yet used.
