[nautilus-actions] Sort actions in the display order

[Pierre Wieser <pwieser src gnome org>]

commit 53b6ae2e8b050d27250da62ea7c7a76b74016344
Author: Pierre Wieser <pwieser trychlos org>

    Sort actions in the display order
    
    Rationale: GConf returns subdirs of the key in a random order. To be sure to display
    actions in the Nautilus context menu in the same order than they are displayed in
    NACT, we sort the actions right after the load operation.
