visual changes:
- removed redundant files user.class.php, calendar.class.php
and backend.class.php.
- converted *all* mysql queries to queries supported by the
database abstraction layer.
- expanded the watchdog to record more information on what
actually happened.
- bugfix: anonymous readers where not able to view comments.
- bugfix: anonymous readers could gain read-only access to
the submission queue.
- bugfix: invalid includes in backend.php
- bugfix: invalid use of '$user->block'
and last but not least:
- redid 50% of the user account system
- anonymous chicken was able to moderate commnets

The only thing left to be done is to tackle (or continue tackling)
the user accounts which in fact is quite some work. :o)
