- list nodes chronological

Commiting my work of last Sunday:

 - removed ban.inc and ban.module and integrated it in account.module
   under the name "access control" --> the ban code was not really up
   to standard so this has now been dealt with.  This refactoring and
   reintegration cuts down the code size with 100 lines too.  :-)
   (The ban.module code was really old and it showed.)

 - added node.module and made the other modules reuse some of this
   code --> cut down the code size of modules by at least 100 lines
   and adds stability.

 - added a status() function to admin.php to display a conform status
   message where appropriate.  See admin.php for usage.

 - removed $theme->control() and made comments.inc handle this itself
   wrapped in a $theme->box().  No need to clutter the themes with
   such complexity --> updated all themes already. :-)

 - some small visual changes to some administration pages to be more
   consistent across different modules.

- simplified some of the node stuff:
    stories can no longer be scheduled -> this functionality will be made
    generic for all nodes

- worked even more on the robustness of include/node.inc

- tidied up the watchdog messages

- simplified book.module so that it is easier to maintain (yet a bit
  less sexy) - the entire module is only 258 lines.

- fixed another bug

- fixed bug in section.module: id -> nid
- fixed bug in book.module: not 100% yet

- removed debug information

"na" appeared when a story didn't have "read more"

- fixed "you-have-to-logout-and-login-before-permissions-change" bug
  (reported by UnConeD)
- added "add node" link to book selection box and made it display the
  current location
- removed tabs and whitespaces from themes - done automatically

- fixed update bug

- removed dead links

- fixed typo in hostname.conf

- visual improvements to example.theme, simplified HMTL code (- 20
  lines)
- made node.inc more robust: it should roll-back when something goes
  fubar and it should work in subdirectories

- removed debug statement

- forgot to remove a debug statement

- fixed issue depricated call-by-reference issues
- fixed small visual glitch in includes/function.inc
- changed SQL tables around a bit to be more consistent
  (result: small changes to a lot of different files)
- improved robustness of includes/node.inc
- improved output of cron.module
- improved output of node.php

- made the node code a bit more rock-solid - needs more work and
  testing!
- you can't add a node with the same title twice within 5 minutes
  (to avoid reposting by accidentically reloading your page after
  having posted)

- fixed small problem in example.theme

- update the linking mechanism: to link to a "node" (ex story) with title
  "fubar", use [[fubar]] or [[fubar|link text]].

- streamlined the book and story module

  added the # votes to the "track your comments" page

Flushing my backlog (in case Natrak wants to make more changes):

 - tidied up some of the code
 - fixed a small problems

would be to support more databases :-)

Changed the error re-direct URL to the same as $site_url in case a user tries to access a sub-directory that does no exist.

- small improvements as well as 2 bugfixes

- fixed home-link when using drupal in a subdirectory
