Accept npm's config variables in package.json

It would be really awesome if we could be able to set NPM's config object for setting bower configurations as well, in addition to env vars and having a package.json like:

package.json

{
  "name": "my-app",
  "private": true,
  "dependencies": {
    "bower": "^1.3.12"
  },
  "config": {
    "bower_directory": "src/vendor",
    "bower_storage__cache": "~/.bower"
  },
  "scripts": {
    "postinstall": "bower install -p",
    "prestart": "bower install --offline",
    "update": "bower update"
  }
}

This would be it really good for development and continuous integration as well, without having to reset these variables for every bower command called (using bower --config flag). Simply running npm install would then inherit all those configurations.

Isn't it a duplicate of your own issue? :) #1626

Just a note: You can use .bowerrc and ENV variables for configuring those variables.

That said, I really like this feature, and it should be as easy to implement as allowing npm_package_bower_ additionally to bower_ prefix for ENV variables.

Would you mind preparing PR with tests for https://github.com/bower/config ?

@sheerun thanks for the support. Actually I believe this complements #1626 in a way that would partially resolve one of its issues.

I have managed to allow npm_package_config_bower as you have mentioned. However, I am not quite sure on how to proceed with the tests considering they would need to start with their own npm instance so the config attribute defined on package.json is evaluated.

Please let me know if you have an idea on what would be the proper way to link that to the main test thread.

Hey. For filesystem tests I think you can use: https://github.com/tschaub/mock-fs I also think it's possible to edit process.env directly in node. No? I think any way is good as long as it is tested somehow.

hey @sheerun let me know if that's ok now. If so, I can then submit a PR. cheers
