A field for storing periods of time - modeled in Python by timedelta. It is stored in the native interval data type on PostgreSQL and as a bigint of microseconds on other backends. Also includes significant changes to the internals of time related maths in expressions, including the removal of DateModifierNode. Thanks to Tim and Josh in particular for reviews.
