[nautilus/wip/csoriano/desktop-split: 50/53] desktop-canvas-view: override canvas container creation

[Carlos Soriano Sánchez <csoriano src gnome org>]

commit 0244e98146f862ea2ebdc5191f1889d36d284a56

    desktop-canvas-view: override canvas container creation
    
    So we can use a subclass for the desktop.
    
    This will be necessary in upcoming patches in order to handle the
    special links on desktop that currently are done special casing inside
    the parent canvas view container.
