Patch to use node tokens instead of user tokens for image filepath

I made a patch to use node tokens instead of user tokens for the saved image filepath

There are more options using node tokens than user tokens and the $node object is available when the tokens are made. node tokens also include several user related tokens.

I especially like using [type]/[yyyy]/[mm] or [type]/[author-uid]/[yyyy]/[mm] for the filepaths.

I know a design decision was made to use user tokens, but if anyone wants to use node tokens in the saved filepath, see the attached patch.

the patch makes the node token list available on the imagefield configure page and is tested and working for date tokens on imagefield uploads.
