Translation File Cleaner: No EOF Newline

[Ragnar-F]

It would be useful if the translation file cleaner would add a newline at the end of each file it generates to comply with GitHub's "policy" that an EOF newline is recommended and sometimes enforced.

Each time a user edits a file directly through GitHub's internal editor, or if their editor is set up to do so, a newline is automatically appended at the end of that file. When running the translation file cleaner afterwards, this newline will disappear. This causes unnecessary noise and bloat in the commit history.
