highlight on “All” first result

in templates/filter/default.php on line 33:

<input type="<?php esc_attr_e( $input_type ); ?>" name="<?php echo $input_name; ?>" id="<?php echo $input_id; ?>" value="-1" />

by adding a “checked” parameter you’d get the highlight effect on “All”, as it should:

<input type="<?php esc_attr_e( $input_type ); ?>" name="<?php echo $input_name; ?>" id="<?php echo $input_id; ?>" value="-1" checked />
