This plugin will send HTTP-headers to the client to ensure that Internet Explorer does not try to display the site in compatibility mode,
which tends to break a lot of themes. This is the default behaviour for a lot of older Internet Explorer versions, when the site is identified
as an intranet site. Some clients may also have the setting activated by other means.
This plugin will also tell Internet Explorer to start Chrome Frame, if that is present, as this will also enable the sites to display in a
proper way.
