[epiphany] Refactored the load status callback of ephy-web-view.c

[Alejandro Garcia Castro <acastro src gnome org>]

commit d60afa35bed002f98996fbdeb6a34ad01cc5b2cf
Author: Alejandro G. Castro <alex igalia com>
Date:   Thu Apr 29 19:25:29 2010 +0200

    Refactored the load status callback of ephy-web-view.c
    
    This patch uses the ephy-embed.c callback code and refactors it in
    just one method in the ephy-web-view that handles all the status
    changes for this object.
    
    Bug #593743
