datetime.date support in 0.8 new timeseries framework

[sadruddin]

Is is the intention that datetime.date would be supported as a valid input type for some methods? I have observed that it is only partially supported. Example, when using 0.8.0b1:

# Works
pandas.BDay().rollforward(datetime.date(2011, 11, 30))
# Doesn't work (returns None)
pandas.Day().rollforward(datetime.date(2011, 11, 30)) 

# Works
pandas.QuarterEnd().rollback(datetime.date(2011, 11, 30))
# Doesn't work (raises Exception, code expected datetime.datetime object)
pandas.YearEnd().rollback(datetime.date(2011, 11, 30))

There is only partial support in these methods for datetime.date. I won't have the time to add sufficient testing that they all work with datetime.date; would need additional development help
