* Returns true or false based on whether doNotTack is enabled. It also takes into account the
* anomalies, such as !bugzilla 887703, which effect versions of Fx 31 and lower. It also handles
* IE versions on Windows 7, 8 and 8.1, where the DNT implementation does not honor the spec.
* @see https://bugzilla.mozilla.org/show_bug.cgi?id=1217896 for more details
* @params {string} [dnt] - An optional mock doNotTrack string to ease unit testing.
* @params {string} [userAgent] - An optional mock userAgent string to ease unit testing.
* @returns {boolean} true if enabled else false
