Add typings

Followed recommendations in [dtslint tool](https://github.com/microsoft/dtslint) and [TypeScript documentation](http://www.typescriptlang.org/docs/handbook/declaration-files/publishing.html).

Took tsconfig.json and tslint.json from @testing-library/dom, although it looks like they just copied the examples in the dtslint docs.

Closes testing-library#60.
