- change scopes to have either variable or model, but not both - change lookup to aggressively read from the model, and not use hasGetter - trap all errors (not just eval errors), so that rendering is smooth. - change error reporting to fire an async error. Now there is no need for using logger/registering the logger. - fix test in polymer that apparently was swalling an error in dart2js-minified. This fix wont be needed once we have codegen.
