This patch fixes the CheckboxesWidget as a replacement for the
MultipleOptionsWidget in "list:reference" fields.
"list:reference" fields use the IS_IN_DB(...,multiple=True) validator. Its
options() method returns possible choices a list of string tuples (<key>,
<label>) to be used in HTML option tags and checkboxes. So the widget has to
convert the current values of the reference field to strings as well before
comparing them to the string <key>s returned by options() - see "value=(k in
values)".
Without the conversion the checkboxes won't show the current values - there
won't be any check marks.
