A number of changes to how traitlets and components work. * Classes can be given as strings, like 'foo.bar.Bar' in the Type and Instance traitlets as well as the get_instances method of Component. This is done to allow for forward declarations. * New IPython.utils.importstring that imports a class from a string, like 'foo.bar.Bar'.
