[gtksourceview/wip/loader-saver] FileSaver: don't check if the file is externally modified



commit 321f1b16b93fa837ca6e2d58715aabbbddceff6e
Author: Sébastien Wilmet <swilmet gnome org>
Date:   Fri Mar 14 18:04:29 2014 +0100

    FileSaver: don't check if the file is externally modified
    
    This will be done only by GtkSourceBuffer, which can keep the previous
    modification time and compare it with the new one.
