fix the db references

I tried using this plugin and it was giving me a database error. It turns out, what used to be wp_categories is now wp_terms, and then columns inside are different as well. So I edited the plugin to use these right db references, but I’m still getting an error. It starts to load the categories, and just keeps listing the first category over and over again, adding a dash in front of it for each line. This is infinite. I hit stop on my browser, and told that first category to use the post template i had created, and hit update. It worked, but the infinite listing isn’t working. Thankfully that was the only post template i needed, but it’d still be nice to have it working properly, and i’m sure anyone else trying to use this plugin on the new versions of WP would appreciate the fix as well.

Cheers.
