Update to version 1.0.2a beta

I've made an update to version 1.0.2a available at my download repository. I've fixed the SQL inject detection for I couldn't use my simpleboard. The SQL inject detection mechanism now only searches formerly vulnerable phpShop variables (->phpShop security issues). I too fixed a wrong query which was from the original phpShop distribution (this was hopefully the last one) in ps_intershipper.php. Please feel free to only download the upgrade package.
