[anjuta] document-manager: Remove obsolete code for tabbing between documents.

[Sebastien Granjoux <sgranjoux src gnome org>]

commit 7a0ec9a3d350068981d7cef6fbbc353ffe107239
Author: Carl-Anton Ingmarsson <ca ingmarsson gmail com>

    document-manager: Remove obsolete code for tabbing between documents.
    
    The code was never used since we didn't set any keybindings for the next and previous
    buffers. It also relied on AnjutaDocman being a GtkNoteBook which is no longer the case.
