CocoMUD client

Since the client has been moved to a single AccessPanel (a text field in which one can type AND see the output at once), the command history isn't available. The arrow keys are used for navigation. Therefore, it's necessary to put other shortcuts on the command history, either:

• Ctrl + up/down arrow keys to navigate into the command history.
• Or a lock system, by pressing a key (like escape) where one could use the arrow keys as usual to move into the history.

Both features can be added as long as they can be changed in the settings.
