Updating examples and adding initial TypeScript bindings for rxjs-jquery

I don't know whether or not this is directly ready for merge, I'm looking for some ideas as to handling the DefinitelyTyped dependencies. I suspect one of the reasons TypeScript wasn't built out for rxjs-jquery was due to third-party dependencies, but as I'm starting to use rxjs-jquery in my own project, having typescript bindings (and working examples) was pretty crucial.

Thanks for providing a great library! I'm excited to use it!
