new "view filefield uploads" permission for private files configurations.

Original patch by bojanz, modified version committed to imagefield by dopry,
port to filefield by myself.

#113900 by myself: Make private downloads work by clearing the field's session variable after storing the file.

never been created by the user but must exist because of CCK's design.

Minimally modified the original patch so that $delta is still listed.

@tod0, test hook_filefield_file.

back porting imagefield preview handling updates. fixing some logic issues with single value uploads, and the
form theme functions. single value fields seem to be working. not sure about multivalue fields... required and
extension validation is still working. try at your own risk.

drupal_render.

filefield HEAD should be DRUPAL-5 compatible. I will branch for DRUPAL-5
once I've tested with DRUPAL-5 cck.

t()'s.

Still only works with 4.7

-- support for formatters
-- scalar as array errors on load
-- scalar errors on delete
plus some bric a brac spacing and documenting.

thanks, dm (http://drupal.org/user/77854), re:

and a special patch for cck that modifies the handling of deleted items, and cleans up
some of the multiple fields special cases...

see: http://drupal.org/node/78417

finally figured out some of the insanity... This one requires a special content.module patch to work that may
break lots of other things....

Almost hopelessly broken :).... There are some UI improvements, and a fix to the hook_field op == load
that was nesting a [0] when files loaded from the database are empty(not in db):.

Need to tackle the widget form soon... any takers?
