Title: Changing scopes and flow API.

This makes some changes to scopes to speed them up/make the code more reliable, reworks the flow API to be more in line with what people want, and cleans up some code to enable these changes to be backward compatible (I think).

Most of the scope work is find-replace (scope.leave() -> wtf.trace.leaveScope(scope)).
