========================================================================
第五部分 一些文件处理方法
files_filter_handler 根据type过滤文件
input_encode_handler 提取input中的文件，并解析
file_manifest_filter_html 根据type过滤文件, 并解析为html or md 文本
link_mtime_to_md 文件增加本地时间参数，避免下载到缓存文件
html_view_blank 超链接
html_local_file 本地文件取相对路径
to_markdown_tabs 文件list 转换为 md tab
