Title: Removing omitempty for TrackOpens and TrackClicks

Removing omitempty for TrackOpens and TrackClicks to make sure the values are transferred to mandrill as false and not omitted. This is because mandrill seems to default to true for these values, and if they are omitted there is no way to turn off click tracking.
