[gedit] Set the document as readonly when with fallback char error.

[Ignacio Casal Quinteiro <icq src gnome org>]

commit 634f604d2850bea4dfeb009dcca2d2050fbbcb5d
Author: Ignacio Casal Quinteiro <icq gnome org>
Date:   Thu Jan 14 18:10:12 2010 +0100

    Set the document as readonly when with fallback char error.
    
    If there are invalid chars set the document as readonly instead
    of non editable view. Also listening to the read-only property
    in the window to update the sensitivity and the window title.
