I updated the code to fix bugs with the body field, cck multi-select fields, and a conflict with the path module. The body field and cck checkboxes should now save correctly.

I implemented a hack to prevent the path from saving to the url_alias table incorrectly. The $node->path is now set to NULL during the node-saving process. I found that if I didn't do this, the module would try to save the path as an array.
