[Zope-CMF] invert security permissions

[alan runyan]

yes!

I think 'viewable' by default would work most certainly work better in the
Dogbowl -- its causing me pain.

in OpenText/Livelink land, anything you create is accessible by default
unless you explicitly modify it not to be.
it sure would be nice to have a policy that took care of this and was
selectable/toggleable.

I would like to be able to goto ZMI Preferences and turn off half the darn
Objects, as well I'm sure some users would like to be able to
turn off 'unrelated' content objects.
