Title: ENHANCEMENT: allow disabling individual items/options in dropdown & child classes

Updated DropdownField.php & GroupedDropdownField.php to facilitate disabling (greying out) individual options in the dropdown list. Other child classes don't need to be updated, they now support disabling as well.
