When installing against a database with conflicting tables the installer...

I noticed that when I tried to reinstall anchor (which FYI I only did because I was mucking around) it ran the installer but failed when it came to creating the tables. There wasn't any error the page would just refresh and ask you to put in a username/email/password.

What this does is if the table already exists drops it.
Oh and it also locks the table just to prevent any nasties.
