CocoMUD client

This feature would allow to capture text in a trigger and place it in a given list. For instance, one could place a trigger on the ooc channel. When text is received, it is displayed in the client (although it can be disabled with mute triggers, see #46). But the user could also display the list of ooc messages and be put into a list, useful for navigation and accessibility. This list could be displayed either using SharpScript (which would allow to associate a macro with it) or through the menu bar.
