Fixes #9, issue in-game commands. Add in_game_commands toggle, in_game_prefix setting option. Create concept of 'admin_nicks' for controlling access. Completely refactor input methods to single message() method to route all input. Parameterize send_command() command and arguments. Add distinction to i/o commands for in-game vs non-in-game calls. Fix motd formatting. Refactor send_command to be more explicit with argument handling. Add IncompleteRead exception handler to util_request (although I'm not sure if it's catching it). util_diff now raises ValueError on bad input instead of returning None. Refactor util_wrap() to add prefix to each line. Update readme. Add unit tests and sample data for testing send_command() and notify_value(). Update
