VERSION 0.1:
- supports tjupt and byrpt.
- torrent page shows torrent downloader/uploader ratio.
- clicking the downup ratio will copy the torrent link.
- automatically loads next page of torrents and show them
on current page, effectively doubling the page size.
VERSION 0.2:
- add funbox from byr.pt to tjupt.org, resize and center images.
- torrent page sort torrent with down/up ratio = NaN to the top.
fix number parsing bug for numbers containing `,`
