[Feature request] Add ".." (go one direcory up) in directory listing

[vort3]

I was looking for something like http-file-server for a while and couldn't find a perfect solution. There are many tools like this and all of them miss some important features (like downloading a folder as zip).

http-file-server is almost perfect, but could you add ".." in directory listing to go to parent directory?

I made a fork which adds this for every folder: https://github.com/muller2002/http-file-server/blob/master/README.md

You have to build with go manually and have to navigate to the default go installtion path and then run http-file-server
