Added some corruption/ hack checks to magic. This required changing quite a bit of code. Let me know if anything goes wrong while running magic.

*Update*
Seems I've been quite busy today. I've finally got round to making a script to automatically generate the patch serial number and put it into action. Before I had to do it by hand each time I edited magic and I usually forgot. This script should now take care of this along with with generating the md5sums for hack checking.
