Close a window by double clicking the upper left icon

Idea: I always try to close windows by double clicking the upper left icon of the window bar. I found a patch for metacity to enable this feature through a blog post also found here: http://blogs.gnome.org/metacity/2008/10/08/double-click-to-close/

Rationale: This is a terrible habbit I formed from being raised on windoze and is made worse by the fact that my employer only has windoze machines. It sounds like there are many people who are interested in this feature and I think it would be a perfect addition to the Linux Mint experience. Though it may be unpleasing to hear for some, I have always thought Mint to be the best of the Linux distros for it's ease of transition from windoze. I'm not saying Mint is superior because it's similar to windoze but rather that Mint is superior for it's inclusion of sane and desirable features that other distros shy away from because they are too windoze-like.
