cordova install command like npm install

Hi, I hope this is the right place to suggest this!
A lot of times when working with cordova I find myself wanting to exclude all the cordova platforms and plugins from my version control (git in my case). A lot of the tools that today's hybrid/web/html5-app developers use, like npm and bower provide install commands. Thus excluded 3rd party code can easily be installed after the project was cloned. Usually a json file keeps track of the packages and their exact versions to install when these commands are run. This allows the developers to keep their repository clean of 3rd party code and ensure that everybody's working with compatible package versions.
To my knowledge cordova does not provide an easy way to achieve this. That's why I would like to see some sort of cordova install command and maybe a cordova.json that keeps track of the installed platforms and plugins and their respective versions, so developers don't need check in cordova code in their repositories or manually keep track of the installed platforms and plugins.

What do you think?

I'm happy to contribute if I can and if you think it's a good idea. I'm fairly accustomed with node.js development so I might be able to help. I'm not familiar with the cordova cli code though.
