// DONE: Provided more options where to place favicon: by the link or by the
// url, before or after, inside or outside the link. However in my opinion
// they all suck except the default. ;)
// Broken images would be messy, but Firefox seems to hide them after a while
// anyway. We do still see the gap from the image's padding though!
// It might be desirable to check each image actually exists/loads, or remove it.
// Is that possible, without making an http request ourselves?
// Third-party host URL detection is implemented leniently, and accordingly
// hostname extraction implemented aggressively, which results in favicons
// being given to unexpected things like bookmarklets which contain a site url.
