[gnome-control-center] window: Reorganize functions

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit a5d3af3a259c4ea9cceb47777790213406a565ff

    window: Reorganize functions
    
    In an attempt to make the CcWindow code more organized and
    structured, this commit reorganizes the source code to match
    a recent pattern:
    
     * Structure declarations, G_DEFINE_TYPE
     * Function prototypes
     * Auxiliary methods
     * Callbacks
     * Vfunc overrides
     * class_init() + init()
     * Public API
