Respect "Do not track" setting in IE

Since Microsoft will remove “Do Not Track” as the default setting In its new browsers (see Microsoft Will Remove “Do Not Track” As The Default Setting In Its New Browsers | TechCrunch), it makes no longer sense to ignore this setting.

This means if someone activated “Do Not Track” in IE11, this person should not be tracked in piwik. The behaviour of IE11 will then be the same as Firefox or Chrome.
