Releases for dependantDropdown

Just repaired the files to match drupal 5,
Most work was on JS side.
Here again it works much nicer if you add the type parameter to the widget_settings hook
I.e.
apply this change on content_inc
line 362
$additions = module_invoke($widget_type['module'], 'widget_settings', 'form', $field['widget'],$type);
instead of
$additions = module_invoke($widget_type['module'], 'widget_settings', 'form', $field['widget']);
