[Zope] new product: NISUserFolder

[Jonothan Farr]

I've created a new product similar to etcUserFolder that authenticates against
an NIS database.

This also improves upon the etcUserFolder product by defining a separate role
for each user group, allowing more fine-grained control of which users have
which permissions.

I've submitted a patch to the collector containing these same changes to
etcUserFolder. If DC decides not to include them I'll release this as a separate
product.

Enjoy!
