nice olly plugin

Here a quick and dirty script to stop on the oep of aspack compressed programs

Start Programmer comments
First it walks threw the program and search for the oep bytes 7561 and 7503 (when breakpoint has been set in a earlier run) if it's found we will set a breakpoint on that eip, then it runs the program and when the breakpoint occurs it does a singlestep to OEP. This script has only been tested on 2 programs so please test it and report the results back.
