Title: Preserve timezone when calling #fix_property_dates.

Before this patch, all dates sent to Mixpanel are considered on
UTC+0. This patch adds the timezone to the string format used to
convert DateTime objects to strings before sending them to Mixpanel.
I have confirmed that Mixpanel is able to parse this format.
See #49.
