Delete 'XVimEvaluatorContext"
Now all the evaluators have context and do not pass it
when creating new evaluators.
We do not have any class named "context" but each evaluators
have properties to hold context like "yankRegister", "argumentString"

Since evaluator stack keeps all the evaluators we can refer any context
by walking back through all the evaluators.

Default implementation of each context property calls its parent recursivly
and find (or create) context value.
(See yankRegister method in XVimEvaluator implementation as an example)
