Rewrites for same class token

This is the usecase I'd like to make workable. I open this as a reference and will try to make a PR sooner or later.
````c#
public class MyClass{

private void MyMethod(){
var myOtherInstanceOfMyClass = RetrieveOtherInstance();
myOtherInstanceOfMyClass.MyOtherMethod();

myOtherInstanceOfMyClass = RetrieveOtherInstance(typeof(MyClass));
myOtherInstanceOfMyClass.MyOtherMethod();

MyClass myOtherAgain= new MyClass();
myOtherAgain.MyOtherMethod();
}

private void MyOtherMethod(){};

}

````

It seems doable as we simply need to rewrite `` and `Typeof(myclass)` and class naming, which is not rewritten when in the same class as of now.

Start by tracing the existing code-rewriting logic for class names and type references in the FastScriptReload repository. Use the example in this issue to check generic MyClass references, typeof(MyClass), and construction or member access within the same class; done means all shown forms are rewritten correctly during hot reload.
