    GbDocumentManager: start on document manager to manage live buffers
    
    The long term idea here is that all the open GtkTextBuffer's will be
    managed by this. I think we may also add a generic document interface
    so that things like glade documents can also be managed here. Not sure
    yet though.
    
    Then, we can attach this buffer manager to the combobox in the
    GbTabStack. At that point, we can dynamically create GbEditorTab or
    GbEditorFrame instances to the documents as needed. You can then just
    display any document easily on any tab stack.
