Title: restrict this header to html files

This is kind of an rfc.

The existing .htaccess file sets this header by default, and unsets it for any types it can determine that don't need it. This is quite a fragile strategy and results in the X-UA-Compatible header being sent quite often.

It would be more robust to send this header only when it is known to be needed - i.e. html only.
