Redmine

Hello,
first of all, thanks for the great work.

I noticed that in the Italian translation, several sentences were not translated, so I translated them.

I used a simple bash script to reorder the keys based on the en.yml file to simplify the task, I hope it will not be a problem to be able to insert the file into the project.

I am currently testing it in the Redmine server that I manage.

Thank you.
