Added Ability to Kill Modules During Scan

[TheTechromancer]

Addresses #750.

During a scan, you can now type kill <module>, e.g. kill nmap and press enter. This will kill the module and remove its events from the queue.

Love it. One thing I would consider is that when BBoT runs, to have an interactive CLI.

That way you have a consistent line that does not change, while the rest of the spam of the logs are still scrolling. Just a thought, and more of a quality of life. I'll see if I can find an example (I'm thinking something like Metasploit in the back of my head)
