Increased accuracy of 1.year by accounting for leap years.  The time extensions are not meant to be super-precise but this seems worth it since otherwise you lose a lot of days doing 40.years.ago.  Closes #1488 [tuxie@dekadance.se]

+
 * Added an exception if calling id on nil to WhinyNil #584 [kevin-temp@writesoon.com]
