Title: fix bug in Rickshaw.Fixtures.Time.ceil(), for month and year units

The problem its fixing is that the second new Date() in ceil was being set in local time to the ceiling unit time and then getTime() was being called on it which meant the returned UTC microseconds are adjusted for the time zone when they shouldnt be.
