not compatible with nsconfig

[farfromrefug]

the webpack templates are not compatible with nsconfig.
https://github.com/NativeScript/nativescript-dev-webpack/blob/master/templates/webpack.typescript.js#L41
As you can see paths for app and appResourcesPath are hard coded and not read from a potential nsconfig file.

@farfromrefug you could post a PR - it seems that you have already pinpointed the issue. It would be likely good to have a default path if no nsconfig options are provided.
