Support all filefield widgets, not just images

Hi, the 6.x module prevents anything besides image content types from being uploaded. I believe this is due mainly to the validator on line 266.

It would be nice to know how to set an alternative validator in the UI.
line 266:
function plupload_imagefield_create_node_from($temp_filepath, $file_name, $options) {
.......
$validators = imagefield_widget_upload_validators($field);
