Fix bug where hours logged to a task wouldn't show up if the defaultlogger variable (hours2) for a project was not the same as the defaultvariable (hours).
Fixed username constraint problem and added two new optional columns: password (if the admin wants to assign a password) and notify (wether the user should receive an email at all "f" "t").
Moved fs::publish_versioned_object_to_file_system.select_file_name out to database specific files, to fix a bug downloading archives in Oracle installations. The bug caused the entire contents of content-repository-content-files to get copied into the temp directory, once for each file in the archive. Great for filling up disk drives.
