Remove reference to typings/index.d.ts

Summary

Typings installs our dependencies in the project folder instead of the feathers-client folder, so we don't need this reference to the local typings.

Thank you! I'm still not sure why the PRs are failing but it'll probably pass again once it is in master. I'm not very familiar with Typescript, so if we merge this and make a release it'll pull in typings for the client automatically right?

Also, related to this: feathersjs/feathers#381. We'll definitely release these client typings but I'm just linking it so that we can revisit if/when we have typings in core that the client can extend.

Yup, it should pull it for the client. I have tested this on a separate feathers/angular2 app.
