[Sébastien Wilmet <swilmet src gnome org>]

    App: remove GtkAccelMap loading and saving
    
    It was added in: commit fc40fc6e3cf6d74cd1f7bc67b67b0ff50332a41c
    
    It is used by GtkUIManager, but GtkUIManager is deprecated (since a long
    time) and gnome-latex is moving away from it by using Amtk, and Amtk
    doesn't support GtkAccelMap.
