eo base - add loop_get for base class

base class objects will ask their parent object to get the loop. this
means it recurses all objects regardless of type until it finds an
object that returns a proper loop object - eg a loop object returns
itself, a window, gfx/ui object returns the mainloop object etc. etc.
