Update to angular beta

[joaogarin]

Would be great to get the repository working agains angular2 beta. I still run into some issues with typescript namely the one with "Typescript Module build failed: TypeError: compiler.parseConfigFile is not a function"

I think there is some issues with some breaking changes on ts-node. I am not sure.

Update ts-node to latest version.
But 👍 for upgrade to beta.0

[joaogarin]

forcing the typescript version to 1.6.2 fixes the issues I was talking about. So only thing remaining is really angular2 beta awesomeness=)

Close once PR #21 gets merged.

the repo has been updated to beta.0 but I still need to update it to beta.1
