Optimized Feed Controllers

[sergeyklay]

Optimized and removed duplicate code.

Now thanks to Controller_Feed_Base::_term and Controller_Feed_Base::_tag typical action is very clean and small :)

    /**
     * Get a list of pages with a specific term
     *
     * @since  1.1.0
     *
     * @uses  Controller_Feed_Base::_term
     */
    public function action_term()
    {
        parent::_term();
    }

Note: Controller_Feeds_Blog extends Controller_Feeds_Base and Controller_Feeds_Page extends Controller_Feeds_Base, not Controller_Feeds_Template
