Mattermost currently does not allow optional parameters in the `Content-Type` of an incoming webhook request. Visual Studio Team Services's Slack integration sends its message with `Content-Type: application/json; charset=utf-8`, whereas Mattermost currently requires precisely `Content-Type: application/json`. This PR relaxes this check, looking only at the media part of the header.
