[Moin-user] Remove all permissions from all users

[Florian Lindner]

Hello,

I want to configure a wiki that is used by only user, who is also superuser and 
granted all rights in acl_rights_before. No content should be accessible for 
other users (help pages e.g. would be fine). But I want to be able to grant 
more permissions on per-page base.

acl_right_default = u"All:"

makes the FrontPage for example still be accessible by an unknown user.

Thanks,

Florian
