Thank you Dan Lake, for patches to TestClient:

* Login command now supports starting location
* Added comment character for script files (either ; or # may be used as first non-whitespace on a line)
* Shout and whisper commands no longer encode extra whitespace to end of messages
* Modified say command to the same format as whisper and shout commands
