DateChooser with Months Combobox

Left field is the Flex's default DateField.
On the right is my extended DateField (and extended DateChooser) - both together add the following features:

• A combobox for changing the selected month.
  
• A nice gray background to the days-of-week row (S M T W T F S).
  
• The # of typed characters is limited to 10 (the maximum for the default mm/dd/yyyy format)

I'll add some explanations later...
