Version 3 released

Version 3 is written in python. Why? Because it was a good language test for me, but also because it is cross platform. On top of that, the installer is now more intelligent and will create the registry keys. The settings for the resize are now stored in a .cfg file rather than in the registry as this makes it easy to work with. The Resize Images that the installer creates is a c program that just opens up the config page.
