#29032: Make gallery images size customizable in the editor

 Now the default parameters for the galleries can be customized (see
 [#28693]), it's not really difficult to allow the images size to be
 The only thing we need to do then is to add our custom size with the
 "available ones":

 add_filter( 'image_size_names_choose', 'custom_image_size_names_choose' );
 function custom_image_size_names_choose( $sizes = array() ) {
         $sizes['gallery-thumb'] = __( 'Gallery thumb' );
         return $sizes;

 The only thing we should be aware of is that the "size" parameter is added
 to the shortcode (imho it shouldn't, because this custom size may not be
 good for any theme we install afterwards).
