Customproperties: Correctly size Date

Old behavior:

1) Add a property of type "Date". DateField inside Value column uses
   the full width.
2) Increase the width of the dialog. Now the size of DateField in
   the Value column only uses the half width.

Solution:

Set a flag if the current type is of Date. So we can correct the size
after a dialog resize action.
