The GtkBuilder extends Gtk.GtkBuilder.prototype to implement a custom automatic signal connection function, which is useful in Seed. It does not provide any methods or types, so there is no need to save it's namespace, as of such it can be imported as follows.
imports.gtkbuilder;
Connects the signals present in the GtkBuilder to the functions present in object. That is to say, a signal with handler name, 'ok_button_clicked' will be connected to the 'ok_button_clicked' property of object.
