Title: Add support for $ignore_time and $ip options on people properties

Mixpanel supports {$ignore_time: true} and {$ip: 0} properties when setting people properties. This tells mixpanel to not update the "$last_seen" property and the user's ip, respectively, when applying the people properties. These properties are in the same part of the dictionary as $distinct_id (outside of the $set dictionary).
