Display origin description when no description is filled
The account moves and lines have a description field that is never filled by document creating moves to avoid duplication. Usually we let the user relay on the origin record name to understand the ledger. But it is not always enough, the origin may have a description field which could be useful for the accountant.
The proposal is to display the origin description is the description field is empty (for moves and lines). Of course it should still be possible to edit the description field (when encoding manually a move entry) and it should not modify the origin description. It should still be possible to search on description fields.
