Add a 'recent things' stack to the Dock

hello boys, girls, cylons, and what nots. Here’s a great little tip for all you intrepid mac users running leopard. It gives you a nice little stack on your dock that displays all your recent apps (right click on it to give you more options) but be warned this requires playing in terminal, if you cut and paste and do nothing else you’ll be fine, but as always procede at your own risk since terminal can also mess things up if you type the wrong thing.
