Filter stencil_force_permalink removes the ability to set query_vars

[wgroenewold]

When I want to add a query var with:

function add_query_var( $public_query_vars ) {
    $public_query_vars[] = 'horse';

    return $public_query_vars;
}

it gets overridden by stencil_force_permalinks. A workaround is

add_filter( 'stencil_force_permalink', function(){return false;} );
