TypeScript typings

[fogzot]

It would be nice to have TypeScript typings included in the htl package. Adding an index.d.ts file with the following content should be sufficient to import and use the package:

export declare const html: { <T extends HTMLElement | Text>(...args: any[]): T, fragment(...args: any[]): DocumentFragment };
export declare const svg: { <T extends SVGElement | Text>(...args: any[]): T, fragment(...args: any[]): DocumentFragment };

Let me know if you want a proper pull request or if the example code above is enough.

I second this request.
