Possible fix for bug #940: Task Calendar.
The maximum year allowed has been increased to 2030 - Do we really need an upper limit?
The date selector has been replaced by the browsers built in date picker.
The highlighting of days on the calendar has been changed slightly.
The selected date now uses the "selected" class for consistency across the site
Highlighting today requires a change to the theme CSS to add a new class "calendar-today"
The glowiron theme has been updated. Other themes have not.
