Title: Generate query string signatures

Most of the time, the original `S3::Signer` class's method of
generating an `Authorization` header value is what you want.
However, there are times when you want to simply pass a URL
around, assuming that the user-agent which will make the
request won't want to use any special HTTP headers. For these
cases, you can use a query string signature.
