Added support for Web Authentication API

Can it do registration without a token yet?

Bookmarks no longer support multiple keywords for the same URL unless the request has different POST data

Is that a joke ?

@Djan GICQUEL Wait, bookmarks save POST data? This doesn't seem like a good idea at all. GET-requests are at least supposed to have no side effects.
