hook_field_formatter() should look to $items['filepath'] as backup if $items['fid'] not present

IMHO: The imagefield_field_formatter() should look to $items['filepath'] as backup if $items['fid'] not present. I needed this to work with a patch I made for CCK Imagefield so it could display a default image (even if this image does not necessarily have a corresponding $fid).

(see attached)

Goes great with patch at:
