Get Dodge Windows Unity Autohide Behaviour For Maximized Windows In Ubuntu 12.04 Precise Pangolin

As you probably know, the window dodge Unity launcher autohide behaviour has been removed from Ubuntu 12.04 Precise Pangolin. Unfortunately, it seems this feature won't make it back into Unity, but thanks to a work-around by WebUpd8 reader Jorge, you can get the dodge windows feature back. Well, almost.
