Bugs fixed in nightly + DB editor

I have found and fixed a bug within the crontab builder, it was not removing the older entries and your crontab would end up with the same entried repeated.

I have also found a bug in the require statement at hte start, and have changed the require to point to the local directory instead of a hardcoded /var/www/html/auto directory.

These are fixed in the latest nightly.

Users downloading the latest nightly will notice a new .pm module db.pm. This is a new Database editing module i am writing that will be portable for use in any perl/postgres environment.

At the moment it allows viewing of the database / tables contained. No bugs are expected but do lodge a bug notice if you are having any problems.
