This method graphically resets the console after its state has been cleared.
Kills the old eventspace, and creates a new parameterization
Also calls the super method.
To change/extend the user's parameterization, ovveride this method, and after the call to the super method returns, change the parameterization. For example, to add a definition of a function, f, to the users' namespace, write this:
(class ...
(inherit user-param)
(rename [super-reset-console reset-console])
(public
[reset-console
(lambda ()
(super-reset-console)
(parameterize ([current-namespace ((in-parameterization user-param current-namespace))])
(lambda ()
(global-defined-value 'f (lambda (...) ...)))))]))
