This adds a "new file" menu item to the nautilus right-click menu for when you right click on a file. Place this file inside `~/.local/share/nautilus/scripts` and name it `new`. This script is useful for when you are using nautilus in list view, because nautilus currently doesn't show this menu item when right clicking on files.
