Got rid of auth_ops_cmdline() (not needed).
auth_ops() is now called in util_ops.inc;
every script in html/ops/ must include util_ops.inc.
Note: for existing projects, the admin web interface
will now show "access denied".
Projects must think about what access control policy they want,
and specify it in project.inc

beneath it.
Otherwise you get "zombie" posts, and e.g. when we should a user's
posts, they might all be hidden.
Also added a script to retroactively clean up these.
