Document package.json fields in the reference

[brodycj]

I can see how there is a reference page for config.xml but don’t see a corresponding reference page for package.json. I think the reference page for Cordova-specific package.json fields is needed.

I also think that how and when the Cordova CLI would update each of the fields in package.json is needed, just like this was already done for config.xml.

This issue is triggered by #1004 (deprecated plugins element in config.xml).

Does anybody know how I can change the "build" key for release and debug builds on package.json? I could not find the docs for this...
