RSS feed torrent links with spaces aren't handled correctly

[SquirrelKiev]

For example, an RSS feed with an item with a url of https://example.com/Super awesome episode.torrent, Taiga will attempt to download https://example.com/Super, which fails. This is particularly an issue on the erai raws RSS feed. Could just replace the spaces in the link with %20 before attempting the request?

URLs cannot contain spaces, though. https://example.com/Super awesome episode.torrent is not a valid URL.

Unlike #1021, this is not about user input, so there shouldn't be a need to allow a more human-friendly syntax. Erai-Raws fixing their RSS feed makes more sense to me than Taiga and other applications adding a workaround for them. Standards exist so that there is prior agreement on how to communicate and we don't have to think about things like this.

That being said, this won't be an issue if v2 ends up using Qt's QUrl class for handling URLs. It works in TolerantMode by default, which accepts unencoded space characters.

Erai didn't seem interested in changing either, will switch to a different feed for now
