Dave Day a870243201 jws: use base64.RawURLEncoding
The Raw (unpadded) version of URL encoding was introduced in Go 1.5.
Since we no longer need to support Go 1.4 (and indeed, Go 1.4 won't work
because of our dependency on golang.org/x/net/context), we can simplify
the base64 encoding/decoding to use this directly.

Fixes golang/oauth2#190.
