feat(client): Add initial TypeScript support

[Awk34]

Notes: serve works, still plenty of TS errors, need to add gulp config, need to add tsd tasks in grunt/gulp, need build, need test, need to add to generator tests

closes #1123

I really want typescript to work with full stack angular, but would like to integrate it with my current system.
Would I have to re-generate the project, then port everything across?

@dolanmiu It depends on how far you have changed things from initial scaffolding. If not a lot, you can back up your project and try scaffolding over your current code. Or you can scaffold a new project and compare the two.
