Configure Play Framework to transpile TypeScript files as a single JavaScript file

[camilosampedro]

In the angular-frontend branch it is being created an Angular2 front-end (TypeScript).

For client side performance it is preferred to transpile TypeScripts server-side instead of compiling client-side. The idea is to provide a single JavaScript main.js transpilation of those TypeScript.

Some help can be found in the play-angular2-typescript project/template.

Beforehand, thank you very much.
