Re-added the code to display 'closed' next to closed sessions; cleaned up the TODO list a bit.
Renamed ui_session.rb to ui_session_interactive.rb in preparation for other ui types
Moved some common functionality into ui_interface.rb
Hooked up the 'ping' function in the 'command' sessions on both client and server sides
Fixed a small overflow bug in the 'ping' code on the dnscat client that would cause an abort() on long inputs (DoS only :) )
Making some headway towards implementing COMMAND_SHELL on the client
removed some debug messages
Merge branch 'master' of ssh://github.com/iagox86/dnscat2
