Put search form anywhere in a page or post.

Beacuse the plugin base function bsc() uses
“echo $form;” to display search form; the search form only shows up at page or post begining.
But sometime we need to put search form anywhere in page or post.

I change the code as follow:
function bsc () {
…
return $form;
}
function sbc_shortcode($atts){
…
$form= sbc($focus, $hide_empty, $search_text, $only_cat, $excluded_cats, $exclude_child, $inall_exclude);
return $form;
}

After this change, you can put shortcode [sbc] anywhere in a page or post.
