Parsing "Last winter" with markTimeRanges and includeRange option turned on sets the end of the range incorrectly

[mightynimble]

"Last winter" parses to <TIMEX3 range="(2015-12-01,2015-03,P3M)" tid="t1" type="DATE" value="2015-WI">last winter</TIMEX3>. The year of the end of the range should be 2016 in this case.
