[Openmcl-devel] startup 'terminal' window

I assume that Phil means that there should be a way of getting rid of  
the Listener. In the MCL based version of AgentSheets we have a end  
user / developer switch (only available through a key file). In end  
user mode you get:

- only application menus (no List tools etc)
- no listener
- all error and warning wrapped up in standard alerts with some some  
syntactic clean up
- disabled debugging tools, i.e., not backtrace etc.

If you want to deploy an app this is pretty important. End users  
really do not want to see or interact with listeners.
