Created basic debugging attack against DISS system that was compiled
with debugging information.

This code is based on the source code for jdb, but most of it is
unecessary and will be removed at a later date to shrink the payload
size. JVMAttack.java features the bulk of the important code.

Code to be attacked must have been compiled with the -g flag, and when
launching the attack, the command line must include tools.jar and
sa-jdi.jar in the classpath, along with the PID of the process to be
attacked as the sole argument.

This program has proved that is likely impossible to retreive the keys
from a running DISS program using the Java JDI alone. An external
debugger will be needed at some point.
