Read only args as combo boxes can now be set to None, if allowed, in the GUI user functions.

The empty string and None are prepended to the combo box choices and data respectively.

Reverted r16189 as this will be implemented at the GUI element level.

The command used was:
svn merge -r16189:r16188 .

The GUI element can decide what to do in this case, for example add a None element to the list!

Check that wiz_read_only is not set if can_be_none is True and a combo box is asked for.

The combo box needs to be editable to clear it - so it returns None. Otherwise if a user selects
one of the values, then they cannot unset it to allow for args of None.
