[UPD] Update ddmrp_product_replace.pot

Some of the main changes included are:
* replacement can be done to a new buffer, instead of changing
  the buffer of the replaced buffer. (new mode "new_buffer")
* In the new mode buffers are related via `replaced_by_id` field.
* Boolean `use_replacement_for_buffer_status` allow to consider
  buffers being replaced in NFP (via on-hand and incoming).
* warnings shown for products being replaced when procuring, and
  procure recommendation is now 0 if the buffer is not
  distributed.
* Views adaptations and improvements.
* Old funtionality kept in mode "use_existing".

[UPD] Update ddmrp_product_replace.pot

…lso for qualified demand.

This way, products replaced by a given buffer can affect the net flow
position of the replacing buffer on the demand side as well.

includes a small fix to avoid singleton errors.

[UPD] Update ddmrp_product_replace.pot

When a replaced buffer is auto-updated its replacement buffers
should also be auto-updated.

[UPD] Update ddmrp_product_replace.pot
