feat(typescript): Play nice with tslib (#895)

PanayotCankov · Plamen5kov · commit fbaab99f791a · 2017-12-18T14:50:34.000+02:00
AngularApp started adding tslib in the web pack project.
This PR will set the __native, __extends and __decorate on the global using Object.defineProperty,
so the tslib won't be able to overwrite them.
Ideally adding tslib to a project should bring support for async/await etc.
