[gedit] Overwrite the change_current_page binding on gedit-notebook.

[Ignacio Casal Quinteiro <icq src gnome org>]

commit 0654e6572e90ff2583f7fb4b528f0e748dd3e428
Author: Ignacio Casal Quinteiro <icq gnome org>
Date:   Sat Aug 8 22:40:58 2009 +0200

    Overwrite the change_current_page binding on gedit-notebook.
    
    Overwrite the change_current_page binding vfunc to manage the wrap around
    by our own, so we can have it when we hide the tabbar for example when
    we are on fullscreen. (Fixes bug #591121)
