[minor-refactor] Add trailing newline to all text files.
Created by: cirosantilli
Present in the large majority of files of each respective type.
The only filetype for which we could be not sure is the .txt because there is only one other, but let's follow the other files and do it.
Bit me when doing perl -lapi -e, needed to change to perl -pi -e, or else newlines were added.
Refactoring command used:
git grep -Ile '' | grep -Ev '^vendor' | xargs perl -lapi -e 's/.*/$&/'-Ile '' to ignore binary files: http://stackoverflow.com/questions/18973057/list-all-text-non-binary-files-in-repo
