Y.Calendar.selectDates fails when passed the maximumDate with minutes/seconds

[mairatma]

#1030 reported a similar bug a few months ago, where calling selectDates with the minimum date wouldn't work, and #1092 fixed it by always setting the date's hour to 12, which is equal to the calendar module's dates.

A similar issue is still happening with the maximumDate in the current (3.15.0) YUI version though. It happens if Y.Calendar.selectDates receives the maximumDate with minutes/seconds/milliseconds in it. For example: "Thu Jul 25 2013 13:20:13". The fix in #1092 transforms this example date to "Thu Jul 25 2013 12:20:13", but that still won't pass the maximumDate check, so the date is not set.

I believe that to fix this we can just replace the:

oDate.setHours(12);

line with

oDate = this._normalizeTime(oDate);

since that will also set minutes/seconds/milliseconds to 0.

If you guys prefer I can do this myself and send a pull request for it, I'm just opening this issue first since I haven't contributed to YUI before.
