Removed chmod/chown's from the Hackathon code. Please notice that:

- The Adodb library contains some chmod's. These have not been removed.
- The 'dbupdate' script contains one more chmod that gets executed when the log files don't exist. This one call has not been removed since the 'dbupdate' script may be executed by root, which could block the log files to other users.
- Other branches should have more instances of these two commands since the old Queue Manager does not exist in the Hackathon branch any more. The old QM contains several chmod/chown's.
