Title: Specify ContentType

Internet Explorer sometimes sends funny accept heade as below.
`Accept: image/gif, image/jpeg, image/pjpeg, image/pjpeg, application/x-shockwave-flash, */*`

In such situation, Content-Type header in response becomes `application/x-shockwave-flash`,
and Internet Explorer renders nothing.

So, gitbucket should specify Content-Type header.
