date 7.x-2.0-alpha5

Notes:
The date repeat widgets have been removed to keep users from trying to change repeating dates into non-repeating dates.
There are now just three widgets, Date Select, Date Text, and Date Popup. Whether or not a date is a repeating date
is now controlled by a field setting.
