[Zeeshan Ali Khattak <zeeshanak src gnome org>]

commit 52c4268dd9fb1a6a4251eec9ec164a535ede4bc9
Author: Zeeshan Ali (Khattak) <zeeshanak gnome org>
Date:   Thu Oct 25 04:32:33 2012 +0300

    Move MainView.(un)select_all to MainViewGeneric
    
    MainView still keeps these methods but only as proxies.
