- improved submit.php:
  it now uses the new category code, incl content bindings.
  You can setup different "categories" which map on a content
  type.  Example:
    review   -> review.module
    article  -> story.module
    column   -> story.module
    announc. -> story.module
    addons   -> file.module
    themes   -> file.module
- "generalised" story.module and book.module's output.
- fixed bug in includes/timer.inc
- fixed glitch in theme example.theme: it said "$how by" but
  the variable $how has never been declared.
- added "drupal development settings" to display some timings
- more work on the categories/topics -> does NOT work yet
