- removed redundant file: a left-over from previous optimizations

A batch of patches:

  - configuration:
    + renamed $db_name to $db_user
    + renamed $db_base to $db_name
  - fixed small diary glitch
  - fixed initial-comment-score problem
  - fixed comment rating bug: improved the API and updated the
    themes
  - removed some tabs from Steven ;)
  - fixed backend warnings and improved robustness
    I'm not happy yet with the headline grabber - it generates
    too many SQL errors.
  - some small cosmetic changes in comment.module
  - fixed minor glitch in format_interval()

- fixed more then 30 typoes (thanks to my Linux spellchecker)

- quickly created a project module (in less then 5 minutes, for the
  records) before crashing into my bed after waay to heavy New Year
  parties while facing the fact I have to get up at 6:45am to go to
  work.
