Packing List views are a bit particular because they use getMovementList.
All the listbox lines are movements. Similarly, some lines can bear
variation categories. It means that the "enabled" TALES test:
  python: cell.isMovement() and not cell.getVariationCategoryList()
is problematic for this view.

For quantity fields, the Base_viewFieldLibrary.my_view_mode_quantity
fits perfectly our usecase.
For price, we need to get price precision from the cell, so
Base_viewFieldLibrary.my_view_mode_price does not fit. On the other hand,
Base_viewTradeFieldLibrary.my_view_mode_price does include the "enabled" TALES,
which we do not want.
We thus create a new "my_view_mode_movement_listbox_price" field in
Base_viewTradeFieldLibrary for this usage.
