Title: be consistent with how we locate the favicon tag, and be more forgiving

[Favicon#Standardization](http://en.wikipedia.org/wiki/Favicon#Standardization) states that `shortcut icon` is the only other value for `rel` that's allowed (other than `icon`) so rather than just match on `\bicon\b` (which could match a false positive) I think it would be better to match explicitly either `shortcut icon` or `icon`.

This prevents issue #6 from cropping up again in future, as well.
