Adopt `potodo` in Makefile

I found a tool named potodo that provides same functionalities with part of our current Makefile commands but has better format. We can consider adopting this tool in our Makefile (or even storing the output as a file and updating it whenever a PR is merged).

• Listing untranslated files

  • make todo

    > make todo           
    for file in *.po */*.po; do echo $(msgattrib --untranslated $file | grep ^msgid | sed 1d | wc -l ) $file; done | grep -v ^0 | sort -gr

• Get overall progress

  • make progress

    > make progress
    4.4%
    

  • potodo | tail -n2 | head -n1 | cut -c 10- | sed 's/[%].*$/%/g'

    > potodo | tail -n2 | head -n1 | cut -c 10- |  sed 's/[%].*$/%/g'
    4.31%
    

Inizia con i comandi del Makefile del repository per todo, fuzzy e progress, quindi confronta il loro output con gli esempi di potodo documentati in questa issue. Verifica come verrebbe invocato potodo nel Makefile e se il suo output debba rimanere il risultato di un comando o essere memorizzato in un file. Il lavoro è completato quando i comandi selezionati per lo stato della traduzione forniscono i risultati previsti nello stile di potodo.
