[Pharo-project] one-click is dead, now we have platform specific builds

tbh, one-click was just cool for mac users... windows and linux users (specially newcomers) where having bad reaction with the structure that the one-click enforces. The new scripts produces structures that can fit better into the platforms where they will run. You can check them here: http://files.pharo.org/platform/ of course, a lot of improvements are possible, this is just the first step :) Esteban
