[ThePirateBayBridge] Repair broken bridge

This is more like a refactor because they dont serve data in plain
html anymore. Instead, the data is available from a json api
at apibay.org

Could possibly expand this bridge because their api has more to give.

I learned about this api by grokking https://thepiratebay.org/static/main.js
and by looking at browser ajax requests.

For some unknown reason they host some static assets at
https://torrindex.net/ which is used by the bridge to render
magnet image and user status image.
