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
```
