Clean up HTML response construct, uppercase UTF-8

IANA has registered UTF-8 as uppercase, hyphenated. The RFC concerning
UTF-8, RFC 3629 also uses this grammar.

RFC 2231 says the Content-Type charset value should be:

    charset := <registered character set name>

RFC 5987 further emphasizes this:

    charset       = "UTF-8" / "ISO-8859-1" / mime-charset

Therefore lowercase "utf-8" in Content-Type responses is technically
incorrect, but case-insensitive according to RFC 2616.

Thanks to pantsucat for researching this with me.
