Support for variables in complex statements

[elijahmanor]

Due to a recent feature (Convert environment vars) the cross-var package can almost be deprecated. The one thing the library could support that cross-env does not yet (to my understanding) is complex statements.

The API for complex statements is to wrap the contents in a string so that all the variables can be replaced and then executed. What do you all think of this API and would it fit well with cross-env? If this type of feature was added to cross-env then cross-var shouldn't be needed anymore.

{
  "version": "1.0.0",
  "config": {
    "port": "1337"
  },
  "scripts": {
    "simple1": "cross-var rimraf public/$npm_package_version",
    "simple2": "cross-var http-server public/$npm_package_version -p $npm_package_config_port",
    "complex": "cross-var \"node-sass src/index.scss | postcss -c .postcssrc.json | cssmin > public/$npm_package_version/index.min.css\""
  }
}

This is actually going to be released soon! It was implemented in #89 and will be released when this is merged: #87

🎉

@kentcdodds well that is great! that means i can re-record both the nps and cross-environment egghead lessons with just cross-env!

And with nps-utils you can uninstall a bunch of the libs because they're supported by default!
