remove json.stringify which causes errors

[green3g]

The json.stringify makes the code fail when using webpack 3 with canjs 3.x. Not sure its even necessary for 2.x.

For instance if I have a component with this:

<p class="hello"><content /></p>

The output looks like this:
<p class=\\\\"hello\\\\"><content /></p>

Also make plugin use canjs 3.x

Hi @roemhildtg, thanks for contributing. Let me check the changes before merging.
I've created this loader for one of the project's that is based on CanJS 2 and WebPack 2+, that's why it might be not compatible with either CanJS 3 or WebPack 3.`

If you want to leave it at v 2.x that is fine with me, I can publish a new package and use that instead. I think it would make sense though, to give it a new major version and publish the same package with a new version.

@roemhildtg I did check your Pull Request with CanJS3 and WebPack3. Based on that I think I cannot remove JSON.stringify from the source code. Without stringifying and escaping the content of the stache template file WebPack will not compile it.

You can check the example usage and configuration of WebPack here: https://github.com/macku/canjs-webpack-demo
Here are the changes applied for the loader. Mostly it's just a clean-up: https://github.com/macku/can-stache-loader/commits/canjs3-webpack3

You can try to use beta release v1.0.0-beta and check how it works with your config.
