Changes

This is a guide to porting an existing activity from GTK2 to [http://developer.gnome.org/gtk3/stable/ GTK3]. It also shows the changes to use the new Sugar toolkit that also now uses [[Features/GTK3|GTK3]]. This guide uses the [http://git.sugarlabs.org/hello-world hello-world] activity as a simple example.
