Marco Antonio J. Costaandmajcosta 86ad401186 add newline at end of file where it's lacking 
.editorconfig already enforces it but it's getting changed piecemeal in
every commit. just get it done with.

the script:
```

find . -type f -not -path "./.git/*" -not -path "./.vs/*" | while read -r file; do
	isFile=$(file -0 "$file" | cut -d $'\0' -f2)
	case "$isFile" in
		(*text*)
			echo "$file is text"
			if [[ $(tail -c 1 "$file" | wc -l) -ne 1 ]]; then
				echo "" >> "$file"
			fi
			;;
		(*)
			echo "file isn't text"
			;;
	esac
done
```
