Zone.JS integration POC #3

Background

Zones are a powerful concept that was invented for the first time a few years ago. Until then it went from just a theory into practice and now it's used in Angular2 change detection. This implementation is supported by the Angular team.
What are zones and why we might need them? A Zone is an execution context that persists across async tasks. You can think of it as thread-local storage for JavaScript VMs.
That means if we run each request in a separate zone we can store part of the injector there and support injection of request scoped components. Furthermore zones add improvements to the error handling and profiling. Having this 'thread-local' storage will enable us to implement declarative transaction management.

Goal

Integrate Zone.JS in the project and check if it works as expected.

Task

• add zone.js as dependency
• run each request in a separate zone
• add support for simple @ThreadLocal storage in components
