Merge pull request #6402 from paranoiase/prev-and-next-quarter
Add prev_quarter and next_quarter methods in Time/Date/DateTime calculations.
Similar to prev_month and next_month, it returns the date with the same day
in the previous or next quarter:
t = Time.local(2010, 5, 8) # => Sat, 08 May 2010
t.prev_quarter # => Mon, 08 Feb 2010
t.next_quarter # => Sun, 08 Aug 2010
Closes #6402
