Add script for sorting and deduplicating motion_list/Labels.txt

[jam1garner]

Currently, motion_list requires hand-sorting to avoid nasty merge conflicts.

In order to remedy it, a script similar to the remove_duplicates.py would need to be written to sort the lines and remove any duplicate entries found.

isn't csvout.sort(key=lambda i: i[1]) this line remove_duplicates.py sorting your values?

[Ajay-Singh-Rana]

are these values to be sorted alphabetically..?
You can assign it to me and i'll start working on it right away.
