CocoMUD client

Accessibility has been tested on a client where there was nothing but an output window. This output field isn't a read-only text field. Whenever the user types in it, the cursor moves at the end of the window. This feature makes navigation much easier, using only the arrow keys. It makes it cleaner for flat/object review in some screen readers, as well.

The pitfall of this navigation is that the command history cannot function in the same way. For that, alternatives should be presented, either with a lock, or with alternative shortcuts.
