Added qBittorrent

[ThiemeH]

Heya 👋

Here is a simple qbittorrent widget. Little side note, I think the cache isn't really working, unsure why

There are helper functions in custom-api, is it maybe an idea to make these available globally? Could be useful for more widgets

Example config:

  widgets:
    - type: qbittorrent
      url: 
      username: 
      password: 
      limit: 5

Hey, this is awesome, thanks for adding.

What do you think about making a "torrent widget" and having different clients that can be configured?
I was implementing a similar widget for Deluge #561 and I think we could reuse the front end for different torrent clients.

Let me know what you think!
