[nautilus] application: add common startup code

[Carlos Soriano Sánchez <csoriano src gnome org>]

commit 23ae53870a39afe43548111b6432db39511a6e97
Author: Carlos Soriano <csoriano gnome org>

    application: add common startup code
    
    So children of nautilus application can chain up to it.
    We leave out the parts that children won't be interested in, like
    the bus manager which only nautilus is owner.
    So far is only used for the opened locations, so it's fine.
