[glom/feature_backup2: 5/6] Document: Avoid a crash when creating the parent directory.

[Murray Cumming <murrayc src gnome org>]

commit 281caea61b240ad6737e0c2bc668ab2d57a92cf3
Author: Murray Cumming <murrayc murrayc com>
Date:   Fri Jul 2 10:11:32 2010 +0200

    Document: Avoid a crash when creating the parent directory.
    
    	* glom/libglom/docment/bakery/document.cc: write_to_disk(): Check the
    	result of Gio::File::get_parent() for null, because that happens if we
    	provide a path instead of a URI.

 	Save as Example: Reset the old file URI and allow auto-saving again.
 
 	* glom/application.cc: on_menu_file_save_as_example(): reset the old file 
 	URI and turn auto-saving back on again, because it makes no sense to leave 
 	the user editing an example document. This is really an export anyway.
 	This allows the user to close the window again after saving as an example.
