    Add a __repr__() method to DynamicModule.
    
    This patch adds a __repr__() method to DynamicModule so that modules provide a
    meaningful string with the typelib path included:
    
    >>> from gi.repository import Gtk
    >>> Gtk
    <gi.module.DynamicModule 'Gtk' from
    '/home/laszlo/Dev/gnome-jh-install/lib64/girepository-1.0/Gtk-3.0.typelib'>
