Scionwest_cp d32fd08e8d MudGame:
- Say command no longer invokes the player.executecommand() method as having the server force player execution of a command messes up their Command Input on the terminal client.
   Now the command instances a new working copy of what ever command it needs to execute and will execute the command directly from within itself. 
   
   Note: All scripted commands and engine Types need to be updated to do this in the future.
