lightning strikes twice

I made a couple of minor modifications to a script outlined at ASPN by Bill Bumgarner to make a great deduping tool for my mp3 collection.

It checks the first couple of thousand bytes of a file for matches, and if it finds a match then checks the whole file. So unlike some other tools, it actually finds byte-for-byte matches.

iTunes, for instance, just finds files with similar song names, which returned a lot of false positives when I tried it out.

This script deletes files, so run some tests using small files in a temp folder first. Use it at your own risk!
