joebp – immuninty debugger script

Howdy!

I made some changes to my break point script to make it more modular and accept arguments and stuff. I normally steer clear of python due to its agonizingly strict syntax, but I suffered through it for you. I use this script every single day when I first load a piece of malware into the debugger as the breakpoints listed are the ones most commonly used by malware (or most any program really).
