Specify render callback when adding templates

[taras]

When you have many templates that each have to execute a callback before rendering, you ended up with something like this

    $main_menu = $this->add( 'template', array(
      'name'      => 'main_menu',
      'path'      => dirname( dirname( __FILE__ ) ) . '/templates',
      'template'  => '/main-menu.php',
    ));

    /**
     * Execute setup_main_menu before rendering main_menu template
     */
    $main_menu->add_action( 'render', array( $this, 'load_main_menu' ) );

    $featured = $this->add( 'template', array(
      'name'      => 'featured',
      'path'      => dirname( dirname( __FILE__ ) ) . '/templates',
      'template'  => '/featured.php',
    ));

    $featured->add_action( 'render', array( $this, 'load_main_menu' ) );

It would be easier and cleaner, if you could specify the render callback via $args

    $main_menu = $this->add( 'template', array(
      'name'      => 'main_menu',
      'path'      => dirname( dirname( __FILE__ ) ) . '/templates',
      'template'  => '/main-menu.php',
      'render'  => array( $this, 'load_main_menu' ),
    ));

    $featured_events = $this->add( 'template', array(
      'name'      => 'featured',
      'path'      => dirname( dirname( __FILE__ ) ) . '/templates',
      'template'  => '/featured.php',
      'render'  => array( $this, 'render_featured' ),
    ));
