Twenty Fourteen: option 'display' as in wp_title for description of site

[michelwppi]

The first test to enhance 2014 as multilingual child theme (as I done for 2010 to 2013) is (very) good BUT
in sidebar.php to display $description you forgot to add second parameter 'display' in

get_bloginfo ('description');

as done in wp_title...

get_bloginfo ('description', 'display');

By using this parameter, get_bloginfo is filterable (apply_filters at end of function) as wp_title used in header...

I think it will be coherent to be done in parent 2014.
