* Net::SSH::CommandStream typos fixed
* Net::SSH::CommandStream cleanup made more robust and refactored
* require 'net/ssh/command_stream' added to various modules

session rather than running exec. This allows targets that do not have a
true "shell" which supports exec to instead return a raw shell session.
