Reverse engineering addons

[Igigog]

I was writing this thing before my rest. This is reverse-engineering of GT Tasks. It is almost done, the only thing that's not written is description of status functor. If you want you can publish it @TheParaziT , but I won't finish the part about status functor any time soon (if at all).

I saved the article. I just don't really know which section to add it to.
