基于simpleui的高级搜索框

效果展示

动态识别每个模型的字段类型，去除了外键搜索，可设置指定的字段和排除字段

        actions['async_advanced_search'] = (
            # (function, name, short_description)
            self.async_advanced_search, 'async_advanced_search', '高级搜索'
        )
        actions['async_clear_search'] = (
            # (function, name, short_description)
            self.async_clear_search, 'async_clear_search', '清除搜索'
        )
        actions['async_querysets_update'] = (
            # (function, name, short_description)
            self.async_querysets_update, 'async_querysets_update', '批量更新'
        )
        return actions

由于使用的是session保存搜索条件，因此需要对model_name进行判断，防止其他模型没有该字段报错，同时无法通过页面内的重置按钮重置搜索条件，需另外编写一个重置按钮。
