TypeScript support

[mazamachi]

Do you have any plan to support using typescript instead of es5?

I often use TypeScript to develop a chrome extension with this kickstart.
It would be better if there is any option to set up supporting TypeScript by Gulp.

I have implemented this feature in mazamachi#1 and plan to release this fork repository as an npm package.
If another package is undesirable to you, I am willing to create a PR to this original repository 😄
Thanks.

Hey @mazamachi

I am currently not using typescript or flow anymore. Neither do I plan to add this to this generator.

Feel free to fork this repository and create a typescript version.
