Title: Force IE compatibility to edge for Intranet sites

By default Internet Explorer is configured to render in compatibility mode, effectively IE 7 mode, when it encounters a known Intranet site. Telling IE to run in "edge" mode will cause IE 9 to run in IE 9 mode, IE 10 to run in IE 10 mode, and so on.
