Content-type for host-meta is wrong

The host-meta file is served with the wrong content-type, which may break some 
parsers.

What steps will reproduce the problem?
1.  dawnrider:activity-streams-perl sivy$ curl -i 
"http://atollia.appspot.com/.well-known/host-meta"
HTTP/1.1 200 OK
Content-Type: text/html; charset=utf-8

What is the expected output? What do you see instead?
