Worker unhandled exception propagation

For dedicated workers, if an error is not handled then it will be propagated up to the parent context and the error reporting process begins again one layer up (e.g., to the window's onerror handler). This allows for errors to be propagated up to the original document giving developers the freedom to choose when and how to handle worker errors.
