Ancestors: Kernel-eem.823

_For now_, rip the emergency evaluator out because it's broken... unless you're using MVC, in which case it just works.

Later work can add an AppRegistry to the _System_ package, so that _Morphic_ can get an emergency evaluator once more. (Emphasis to emphasise that an emergency evaluator is not Kernel's concern. #primitiveError: probably ought to go into System.)
