Typechecker doesn't work with Vue.js single file components.

I've set up typechecker, it works fine, but only with `*.ts` files. It doesn't work with `*.vue` [Single file components](https://vuejs.org/v2/guide/single-file-components.html) at all.

I've added the following lines to my `tslint.json` file But it didn't change anything:

```
"include": [
"src/**/*.ts",
"src/**/*.vue"
]
```

It seems that tslint is not able to parse the JS code that's wrapped in `` tags. Is there any workaround? I know that in Webpack they use some trick to pass the content of the script tag into typescript loader. But it's a Webpack specific solution, so I'm afraid that here we have to use a different approach.

I'm not sure is it a bug or is it just a missing feature... and is it an issue related to the fuse-box-typechecker or is something to be implemented directly in the VueComponentPlugin?

Here's my repository, so that you could reproduce: https://github.com/wujekbogdan/fuse-vue-ts/tree/typechecker

Reproduce the problem using the linked typechecker branch and inspect tslint.json alongside the VueComponentPlugin integration. Trace how TypeScript is passed only *.ts files, then determine how the script content inside *.vue files should be handled. Done means TypeScript in Vue single-file components is typechecked successfully.
