Defer the load / creation of configuration UI with changes to
e_preferences_window to take factory callbacks and store a reference to the shell. - This makes start-up substantially faster, particularly on Atom (eg.). Remove a number of idle handlers used to create these UIs in the first instance, cleaning the code.
