Crash when run a demo, then press ESC back to terminal, then run cls

[FreeBlues]

On Mac, do like below:

1. Run a demo;
2. Press ESC back to terminal;
3. Run command cls;
   It will crash

Confirmed. This happens every time the cls command is called on current master

Fixed. The command system will later be rewritten, so things like this won't occur later
