Add primary media type for font

[cj.knight@…]

The IANA has deprecated the use of the application MIME type for fonts in favour of a primary font type.

Source: ​https://www.iana.org/assignments/media-types/media-types.xhtml#font - (In page search for "deprecated" to find the old entries).

To become compliant, the mime.types file would have the line:

application/font-woff      woff; 

replaced with

font/woff                 woff;
font/woff2                woff2;

Which additionally adds WOFF2 support as per the IANA listing. I note that Google Fonts already serves fonts with this new MIME type.

IMHO, I suggest to add new mime-types and save old one for compatibility
