    document-manager: bgo#698036 - Close Other Tabs enhancement
    
    Added a "Close Others" option to the notebook's popup menu. The menu requires to be generated manually 
because of GtkNotebook's restrictions; doing this in anjuta_docman_create_tab_popup function inside 
anjuta-docman.c. The menuitems are connected to on_tab_popup_click and 
on_close_other_file_activate_from_popup. The menu is destroyed if idle using gtk_widget_destroy.
