Merge PO files conveniently via scripts (#2070)

* Add files via upload

This script can merge the post-translation order wrong PO files in the correct order!

* Update and rename merge.py to MERGE.py

Changed the name to all caps to make it prominent

* Update MERGE.py

* Update and rename MERGE.py to Reorganize-po-sequence.py

rename

* Reorganize-po-sequence

Usage: Reorganize-po-sequence.sh base_file new_file output_file
base.po is the PO file within the repo with the correct order
new.po is your translated PO file but may not be in the correct order
