ppid, blockdlls, and bugfixes

This release introduces two new commands that modify post-exploitation jobs that require sacrificial processes. Now, we can spoof the parent process of these jobs, as well as block any non-Microsoft signed dlls from loading into those processes. Last but not least is a bug fix that's been a long time in the making. Now, if you sleep an agent to 0 seconds, you will receive output from that post-ex job.
