Add a typescript-template repo

Is your feature request related to a problem? Please describe. Many people want to use Svelte with Typescript. With svelte-preprocess, a fitting rollup-config and Svelta Beta from VSCode this is working pretty good already. But there is no template devs can degit to get a quick start.

Describe the solution you’d like Add a sveltejs/typescript-template similar to https://github.com/sveltejs/template with some instructions on how to get Typescript running. After some iterations and feedback one could even think about a blogpost on the official website.

Describe alternatives you’ve considered Explaining the same things in Discord and various Github issues over and over again.

How important is this feature to you? Important to get the word out that Typescript support is in a good state now.

OK, that should be good now:

npx degit orta/template#ts
node scripts/setupTypeScript.js

This is what is needed to set up the repo for TS: https://github.com/orta/svelte-ts-template-example/blob/master/scripts/setupTypeScript.js

I’m in favour of 1 also: the docs could be something like:

If you want to covert this repo to a TypeScript project run:

node scripts/setupTypeScript.js test-template

Otherwise you can delete the scripts directory.
