#4 With no guest account a lot of in_array errors

[Anonymous]

I installed version 0.6b1 without any Guest Account.
That gives a lot of ugly error messages basically all
in_array error due to wrong data type in second
argument. By logging in and reloading the ugliness
disappears, seamingly with no harm done.

It seems like there isn't a proper current_user if
there is no auth_user and no guests.

I patched this by making all the statements using
$current_user['group'] an if-block (condition of course
that $current_user is not null) and a similar patch in
is_Auth, so that a null user will return false without
any error messages. I'm not very familliar with the
code, so I admittingly feel somewhat uneasy by this fix.

Really great code otherwise, this far.
